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 railtorail 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 ultralow input bias current.
These features make the TSZ12x family ideal for sensor interfaces, batterypowered applications and portable applications.
