Optimized for battery-powered, ultra-long-life applications, the TS1003 and TS1005 NanoWatt Analog series op amps from Touchstone Semiconductor work from a single 0.8 to 5.5 V source. The micro-power devices are priced at $0.35 in 1K-piece quantities and come in SC70-5 packages.
The TS1005 is the industry’s lowest-power 20-kHz gain–bandwidth product (GBWP) op amp, drawing 1.3 µA, while the TS1003 draws just 0.6 µA and has a 4-kHz GBWP. Both versions have a typical input bias current of 2 pA and rail-to-rail I/O stages, and are fully specified over a −40°C to 85°C range. Free samples and demo boards (TS1005DB, TS1003DB) are available on request.
