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 opamps 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.

SOT23-8

SO-8

MiniSO-8

TSSOP-14

TSSOP-16

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.

1.All voltage values, except differential voltages are with respect to network ground terminal.

2.Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.

3.VCC-Vin must not exceed 6 V, Vin must not exceed 6V.

4.Input current must be limited by a resistor in series with the inputs.

5.Short-circuits can cause excessive heating and destructive dissipation.

6.Rth are typical values.

7.Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins floating.

8.Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating.

9.Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to ground.
