DescripTion
High Temperature 175°C Dual 100MHz, Rail-to-Rail Input and Output, Ultralow 1.9nV/ √Hz Noise, Low Power Op Amp The LT®6203X is a dual low noise, rail-to-rail input and output unity gain stable op amp that features 1.9nV/√Hz noise voltage and draws only 2.5mA of supply current per amplifier. These amplifiers combine very low noise and supply current with a 100MHz gain bandwidth product, a 25V/µs slew rate, and are optimized for low supply signal conditioning systems. These amplifiers maintain their performance for supplies from 2.5V to 12.6V and are specified at 3V, 5V and ±5V supplies. Harmonic distortion is less than – 80dBc at 1MHz making these amplifiers suitable in low power data acquisition systems. These devices can be used as plug-in replacements for many op amps to improve input/output range and noise performance. The LT6203X is a member or a growing series of high tem- perature qualified products offered by Linear Technology®. For a complete selection of high temperature products, please consult our website, www.linear.com. The LT6203X comes in an 8-pin SO package with standard dual op amp pinout. The LT6203X is also available as dice. L, L T , L TC, L TM, Linear Technology and the Linear logo are registered trademarks of Analog Devices, Inc.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Inputs are protected by back-to-back diodes and diodes to each supply. If the inputs are taken beyond the supplies or the differential input voltage exceeds 0.7V, the input current must be limited to less than 40mA. Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. Note 4: The LT6203X is guaranteed to meet specified performance from –40°C to 175°C. Note 5: Matching parameters are the difference between the two amplifiers of the LT6203X. CMRR and PSRR match are defined as follows: CMRR and PSRR are measured in µV/V on the identical amplifiers. The difference is calculated between the matching sides in µV/V. The result is converted to dB. Note 6: Minimum supply voltage is guaranteed by power supply rejection ratio test. Note 7: Output voltage swings are measured between the output and power supply rails. Note 8: This parameter is not 100% tested. Note 9: Full-power bandwidth is calculated from the slew rate: FPBW = SR/2πV P Note 10: Differential gain and phase are measured using a Tektronix TSG120YC/NTSC signal generator and a Tektronix 1780R Video Measurement Set. The resolution of this equipment is 0.1% and 0.1°. Ten identical amplifier stages were cascaded giving an effective resolution of 0.01% and 0.01°. The l denotes the specifications which apply over –40°C < TA < 175°C temperature range. VS = ±5V; VCM = VOUT = 0V, unless otherwise noted. (Note 4)
