Description
The TSV6292, TSV6293, TSV6294 and TSV6295 dual and quad operational amplifiers offer a high bandwidth of 1.3 MHz while consuming only 29 µA. They must be used in a gain configuration (equal or above +4 or -3). The TSV629x series features low voltage, low power operation and rail-to-rail input and output. The devices also offer an ultra-low input bias current and low input offset voltage. The TSV6293 (dual) and TSV6295 (quad) have two shutdown pins for reduced power consumption. These features make the TSV629x family ideal for sensor interfaces, battery supplied and portable applications, as well as active filtering. Table 1. Device summary

2 Absolute maximum ratings and operating conditions
Table 2. Absolute maximum ratings (AMR)
- All voltage values, except differential voltages are with respect to network ground terminal.
- Differential voltages are the non-inverting input termi nal with respect to the inverting input terminal.
- V CC-Vin must not exceed 6 V, Vin must not exceed 6V.
- Input current must be limited by a resistor in series with the inputs.
- Short-circuits can c ause excessive heating and destructive dissipation.
- Human body model: 100 pF discharged through a 1.5 k Ω resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
- Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
combinations with other pins floating.
- Charged device model: all pins plus package ar e charged together to the specified voltage and then
discharged directly to ground. Table 3. Operating conditions

4.2 Rail-to-rail input
The TSV629x are built with two complementary PMOS and NMOS input differential pairs. The devices are guaranteed without phase reversal.

4.5 Shutdown function (TSV6293, TSV6295)
±200 mV (Figure 21 and Figure 22 show the test configurations). Figure 21. Test configuration for turn-on time Figure 22. Test configuration for turn-off time Figure 23. Turn-on time, V CC =5V , Figure 24. Turn-off time, V CC =5V ,
4.6 Driving resistive and capacitive loads
- IGainI ≥ 3 in an inverting configuration (CL = 20 pF , RL = 100 kΩ) or IgainI ≥ 10 (CL = 100 pF , RL = 100 kΩ)
- Gain ≥ +4 in a non-inverting configuration (CL = 20 pF , RL = 100kΩ) or gain ≥ +11 (CL = 100 pF , RL= 100 kΩ) As these operational amplifiers are not unity gain stable, the TSV62x (29 µA, 420 kHz) or TSV63x (60 µA, 880 kHz) – which are unity gain stable – might be a solution for your application.
