High merit factor (1.15 MHz for 45 uA) CMOS op-amps

The TSV52x and TSV52xA series of operational amplifiers offer low voltage operation and rail-to-rail input and output. The TSV521 device is the single version, the TSV522 device the dual version, and the TSV524 device the quad version, with pinouts compatible with industry standards.

The TSV52x and TSV52xA series offer an outstanding speed/power consumption ratio, 1.15 MHz gain bandwidth product while consuming only 45 μA at 5 V. The devices are housed in the smallest industrial packages.

These features make the TSV52x, TSV52xA family ideal for sensor interfaces, battery supplied and portable applications. The wide temperature range and high ESD tolerance facilitate their use in harsh automotive applications.
