Description
The TSV622, TSV623, TSV624 and TSV625 dual and quad operational amplifiers offer low voltage, low power operation and rail-to-rail input and output. The TSV62x series features an excellent speed/power consumption ratio, offering a 420 kHz gain bandwidth product while consuming only 29 µA at a 5 V supply voltage. These op- amps are unity gain stable for capacitive loads up to 100 pF . They also feature an ultra-low input bias current and low input offset voltage. TSV623 (dual) and TSV625 (quad) have two shutdown pins in order to reduce power consumption. These features make the TSV62x family ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering. TSSOP-14 MiniSO-8 SO-8 SOT23-8 TSSOP-16

2 Absolute maximum ratings and operating conditions
Table 1. 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 2. Operating conditions
