TS1005 Operational Amplifier

Touchstone's TS1005 a low power, 20 kHz gain bandwidth, precision CMOS operational amplifier designed to operate over a supply voltage range from 0.8 V to 5.5 V. Fully specified at 1.8 V and consuming 1.3 µA supply current, the TS1005 is optimized for ultra-long-life battery-powered applications.

The TS1005 is Touchstone’s fifth operational amplifier in its “NanoWatt Analog™” high-performance analog integrated circuit portfolio. The TS1005 exhibits a typical input bias current of 2 pA, and rail-to-rail input and output stages.

The TS1005’s combined features make it an excellent choice in applications where very low supply current and low operating supply voltage translate into very long equipment operating time. The devices are TS1005 fully specified over the industrial temperature range (−40°C to 85°C), and are available in PCB-space saving, 5-lead SC70 packages.
