Touchstone claims new op amps cut power requirements in half

Touchstone Semiconductor Inc. has added two new devices to its NanoWatt operational amplifier family: the TS1002 dual and TS1004 quad operational amplifiers.

According to Touchstone, the TS1002 and 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. They are designed to cut power requirements at least in half compared to any other amplifier, the company said.

The TS1002 and the TS1004 are optimized for ultra-long-life, battery-powered applications,

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

Pricing:  TS1002 prices start at $1.05 each in 1000-piece quantities and TS1004 prices start at $1.50 each in 1,000 piece quantities.

Availability: The product is in stock and available from Future Electronics.
