FEATURES Single 0.65V to 2.5V Operation Supply current: 0.6 μA per amplifier (typ) Offset voltage: 0.5mV (typ) Low TCVOS: 10µV/°C (typ) AVOL Driving 100kΩ Load: 90dB (min) Unity Gain Stable Rail-to-rail Input and Output No Output Phase Reversal Packaging: TS1002 – 8-pin MSOP TS1004 – 14-pin TSSOP APPLICATIONS Battery/Solar-Powered Instrumentation Portable Gas Monitors Low-voltage Signal Processing Nanopower Active Filters Wireless Remote Sensors Battery-powered Industrial Sensors Active RFID Readers Powerline or Battery Current Sensing Handheld/Portable POS Terminals DESCRIPTION The TS1002 and the TS1004 are the industry’s first and only dual and quad single-supply, precision CMOS operational amplifiers fully specified to operate at 0.8V while consuming less than 0.6µA supply current per amplifier. Optimized for ultra-long-life battery-powered applications, the TS1002 and the TS1004 join Touchstone’s TS1001 operational amplifier in the “NanoWatt Analog™” high- performance analog integrated circuits portfolio. Both op amps exhibit a typical offset voltage of 0.5mV, a typical input bias current of 25pA, and rail-to-rail input and output stages. The TS1002 and the TS1004 can operate from single-supply voltages from 0.65V to 2.5V. The TS1002/TS1004’s combined features make either an excellent choice in applications where very low supply current and low operating supply voltage translate into very long equipment operating time. Applications include: nanopower active filters, wireless remote sensors, battery and powerline current sensors, portable gas monitors, and handheld/portable POS terminals. The TS1002 and the TS1004 are fully specified at VDD = 0.8V and over the industrial temperature range (−40°C to +85°C). The TS1002 is available in PCB-space saving 8-lead MSOP surface-mount packages. The TS1004 is available in a 14-pin TSSOP package.
