Description
The TSZ12x series of high precision operational amplifiers offer very low input offset voltages with
virtually zero drift.
TSZ121 is the single version, TSZ122 the dual version, and TSZ124 the quad version, with pinouts compatible with industry standards.
The TSZ12x series offers rail-to-rail input and output, excellent speed/power consumption ratio, and 400 kHz gain bandwidth product, while consuming less than 40 µA at 5 V. The devices also feature an ultra-low input bias current.
These features make the TSZ12x family ideal for sensor interfaces, battery-powered applications and portable applications.

Notes:
(1)All voltage values, except the differential voltage are with respect to the network ground terminal.
(2)The differential voltage is the non-inverting input terminal with respect to the inverting input terminal.
(3)Vcc - Vin must not exceed 6 V, Vin must not exceed 6 V
(4) Input current must be limited by a resistor in series with the inputs.
(5) Rth are typical values.
(6)Short-circuits can cause excessive heating and destructive dissipation.
(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 cap 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.
