Offering Four User-Programmable Operating Modes, the New TS7001 is Performance-Priced at $1.15.
Touchstone Semiconductor announced the immediate availability of the TS7001, its newest 12-bit 187.5-ksps analog-to-digital converter (ADC) that can be used as a drop-in upgrade to the Analog Devices AD7887A. The TS7001 is a 50% smaller footprint and is also 1.5x faster versus the AD7887B in an SOIC-8.
Priced at $1.15 in 1,000 piece quantities, the new Touchstone TS7001 is $3 less expensive than the Analog Devices’ AD7887B and $2 less expensive than its AD7887A. In addition to all other Touchstone Semiconductor ICs, the TS7001 is in stock and ready to ship from Digi-Key, Touchstone’s authorized distributor.
Packaged in a MSOP-8, the TS7001 combines a high-speed 3-wire serial digital interface and an internal ±0.5%-initial accuracy +2.5V reference. Operating from +2.7V to +3.6V supplies, it consumes approximately 3mW when converting at 187.5ksps.
The new TS7001’s features include:
- A $1.15 price at 1k-piece quantities: $3 less than the AD7887B and $2 less than AD7887A.
- 3-mW power consumption at 187.5ksps while operating from a single +2.7V to +3.6V.
- One or two analog inputs each with an input range from 0V to VREF or 0V to VDD.
- Four user-programmable, low-power operating modes including auto standby and auto power down.
- ±1LSB INL performance
- Shutdown-mode supply current: 1μA (max).
- -40 to +85 °C operating temperature range.
- An integrated 2.5-V, ±0.5%, 30ppm/°C reference
The TS7001 is an ideal choice for an easy-to-use 12-bit ADC in low-power, industrial, process control and data-acquisition applications. Some portable and fixed-form-factor applications for the TS7001 include: optical sensors, touch panels, personal digital assistants, programmable logic controllers and medical instrumentation.
