Touchstone Semiconductor TS7001 2-Channel, 12-Bit SAR ADC

Touchstone Semiconductor announced the TS7001, its newest 12-bit 187.5-ksps analog-to-digital converter (ADC) that can be used as a 1.5x faster/50% lower INL drop-in upgrade to the Analog Devices AD7887A. The TS7001 is a 50% 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 and packaged in a MSOP-8, the TS7001 combines a 10-MHz track-and-hold (T/H), 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 also include:

• 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°C 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, stand-alone 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.

Easy interface with popular Microcontrollers or DSPs

To facilitate easily the dynamic performance evaluation of the TS7001 SAR ADC or any of Touchstone Semi’s other SAR ADCs, the Company makes available a plug-and-play FFT data acquisition/capture kit – the TSDA-VB kit (Please reference TSDA-VB-Kit-ND) at $175 each. The kit’s easy-to-use GUI makes data capture to the TS7001DB or any other Touchstone Semi data converter product demo board quick-and-easy.
