The LT1208/LT1209 feature reduced input offset voltage and higher DC gain than devices with comparable bandwidth and slew rate. Each amplifier is a single gain stage with outstanding settling characteristics. The fast settling time makes the circuit an ideal choice for data acquisition systems. Each output is capable of driving a 500Ω load to ±12V with ±15V supplies and a 150Ω load to ±3V on ±5V supplies. The amplifiers are also capable of driving large capacitive loads which make them useful in buffer or cable driver applications. The LT1208/LT1209 are members of a family of fast, high performance amplifiers that employ Linear Technology Corporation’s advanced bipolar complementary processing.

CCHARA TERISTICSUWATYPICALP E RFOR CE Gain-Bandwidth and Phase Margin Total Harmonic Distortion vs Supply Voltage Slew Rate vs Supply Voltage vs Frequency USA OPPLICATI WU UI FOR ATIO Layout and Passive Components As with any high speed operational amplifier, care must be taken in board layout in order to obtain maximum perfor- mance. Key layout issues include: use of a ground plane, minimization of stray capacitance at the input pins, short lead lengths, RF-quality bypass capacitors located close to the device (typically 0.01µF to 0.1µF), and use of low ESR bypass capacitors for high drive current applications (typically 1 µF to 10 µF tantalum). Sockets should be avoided when maximum frequency performance is re- quired, although low profile sockets can provide reason- able performance up to 50MHz. For more details see Design Note 50. The parallel combination of the feedback resistor and gain setting resistor on the inverting input combine with the input capacitance to form a pole which can cause peaking. If feedback resistors greater than 5k are used, a parallel capacitor of value C F ≥ RG × CIN/RF should be used to cancel the input pole and optimize dynamic performance. For unity-gain applications where a large feedback resistor is used, CF should be greater than or equal to CIN. Capacitive Loading The LT1208/LT1209 amplifiers are stable with capacitive loads. This is accomplished by sensing the load induced output pole and adding compensation at the amplifier gain node. As the capacitive load increases, both the bandwidth and phase margin decrease so there will be peaking in the frequency domain and in the transient response. The photo of the small-signal response with 1000pF load shows 50% peaking. The large-signal response with a 10,000pF load shows the output slew rate being limited by the short-circuit current. To reduce peaking with capaci- tive loads, insert a small decoupling resistor between the output and the load, and add a capacitor between the output and inverting input to provide an AC feedback path. Coaxial cable can be driven directly, but for best pulse fidelity the cable should be doubly terminated with a resistor in series with the output.

USA OPPLICATI WU UI FOR ATIO Input Considerations Resistors in series with the inputs are recommended for the LT1208/LT1209 in applications where the differential input voltage exceeds ±6V continuously or on a transient basis. An example would be in noninverting configura- tions with high input slew rates or when driving heavy capacitive loads. The use of balanced source resistance at each input is recommended for applications where DC accuracy must be maximized. Transient Response The LT1208/LT1209 gain-bandwidth is 45MHz when mea- sured at 100kHz. The actual frequency response in unity- gain is considerably higher than 45MHz due to peaking AV = –1 CL = 1000pF 1208/09 AI01 AV = 1 CL = 10,000pF 1208/09 AI02 Small-Signal Capacitive Loading Large-Signal Capacitive Loading caused by a second pole beyond the unity-gain crossover. This is reflected in the 50° phase margin and shows up as overshoot in the unity-gain small-signal transient re- sponse. Higher noise gain configurations exhibit less overshoot as seen in the inverting gain of one response. The large-signal response in both inverting and non- inverting gain show symmetrical slewing characteristics. Normally the noninverting response has a much faster rising edge due to the rapid change in input common- mode voltage which affects the tail current of the input differential pair. Slew enhancement circuitry has been added to the LT1208/LT1209 so that the falling edge slew rate is balanced.

USA OPPLICATI WU UI FOR ATIO Low Voltage Operation The LT1208/LT1209 are functional at room temperature with only 3V of total supply voltage. Under this condition, however, the undistorted output swing is only 0.8VP-P . A more realistic condition is operation at ± 2.5V supplies (or 5V and ground). Under these conditions, at room tem- perature, the typical input common-mode range is 1.9V to –1.3V (for a VOS change of 1mV), and a 5MHz, 2VP-P sine wave can be faithfully reproduced. With 5V total supply voltage the gain-bandwidth is reduced to 26MHz and the slew rate is reduced to 135V/µs. Power Dissipation The LT1208/LT1209 combine high speed and large output current drive in small packages. Because of the wide supply voltage range, it is possible to exceed the maxi- mum junction temperature under certain conditions. Maximum junction temperature (T J) is calculated from the ambient temperature (TA) and power dissipation (PD) as follows: LT1208CN8: T J = TA + (PD × 100°C/W) LT1208CS8: T J = TA + (PD × 150°C/W) LT1209CN: T J = TA + (PD × 70°C/W) LT1209CS: T J = TA + (PD × 100°C/W) Maximum power dissipation occurs at the maximum supply current and when the output voltage is at 1/2 of either supply voltage (or the maximum swing if less than 1/2 supply voltage). For each amplifier PDMAX is as follows: Example: LT1208 in S8 at 70°C, VS = ±10V, RL = 500Ω DAC Current-to-Voltage Converter The wide bandwidth, high slew rate and fast settling time of the LT1208/LT1209 make them well-suited for current- to-voltage conversion after current output D/A converters. A typical application with a DAC-08 type converter (full- scale output of 2mA) uses a 5k feedback resistor. A 7pF compensation capacitor across the feedback resistor is used to null the pole at the inverting input caused by the DAC output capacitance. The combination of the LT1208/ LT1209 and DAC settles to less than 40mV (1LSB) in 140ns for a 10V step.
