Touchstone intros TS7001 two-channel, 12-Bit SAR ADC

USA: Touchstone Semiconductor, a developer of high-performance, low power analog integrated circuit solutions, 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 1.5x faster/50 percent lower INL drop-in upgrade to the Analog Devices AD7887A.

The TS7001 is a 50 percent smaller footprint and is also 1.5x faster versus the high-grade 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 10-MHz track-and-hold (T/H), a high-speed three-wire serial digital interface and an internal ±0.5 percent-initial accuracy +2.5V reference. Operating from +2.7V to +3.6V supplies, it consumes approximately 3mW when converting at 187.5ksps.
