Touchstone's TS1002 Low-Power Dual Op Amp

Touchstone's two new low-power op amps--the TS1002 dual and TS1004 quad--cut power requirements in half compared to other amplifiers.

Touchstone Semiconductor, Inc., a developer of high-performance analog integrated circuit solutions, today announced the newest members of its operational amplifier family: the TS1002 dual and TS1004 quad operational amplifiers.

They 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. They are designed to cut power requirements at least in half compared to any other amplifier.

Optimized for ultra-long-life, battery-powered applications, the TS1002 and the TS1004 join the TS1001 single-supply operational amplifier in Touchstone’s “NanoWatt Analog™” high-performance analog integrated circuits portfolio.

The combination of low supply current, low power and a small footprint make these op amps ideal choices for applications where very low supply current and low operating supply voltage translate into very long equipment operating time.

Key Specifications:

  •     Single 0.65V to 2.5V Operation
  •     Supply current: 0.6μA 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

The TS1002 and the TS1004 are fully specified at VDD = 0.8V and over the industrial temperature range of −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. TS1002 prices start at $1.05 each in 1000-piece quantities and TS1004 prices start at $1.50 each in 1,000 piece quantities. The product is in stock and available from Future Electronics.

Free samples and free demo boards are available to qualified engineers. The products are part of Touchstone Semiconductor’s NanoWatt Analog™ high-performance analog integrated circuits portfolio.
