Description
The TSV622, TSV622A, TSV623, TSV623A, TSV624, TSV624A, TSV625, and TSV625A dual and quad operational amplifiers offer low voltage, low power operation, and rail-to-rail input and output. The TSV62x/TSV62xA series feature an excellent speed/power consumption ratio, offering a 420 kHz gain bandwidth product while consuming only 29 µA at 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 to reduce power consumption. These features make the TSV62x/TSV62xA family ideal for sensor interfaces, battery-supplied and portable applications, and active filtering. TSSOP14 MiniSO8/MiniSO10 SO8 TSSOP16 Table 1.

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
