12-Bit SAR ADC Offers 4 User-Programmable Operating Modes

12 bit 187.5 ksps ADC boasts a 50% smaller footprint and is 1.5x faster than other SOIC-8’s.

Touchstone’s new TS7001 is a 12 bit 187.5 ksps ADC that boasts a 50% smaller footprint and is 1.5x faster than other SOIC-8’s. Packaged in a MSOP-8, the ADC combines a 10 MHz T/H, a high-speed 3-wire serial digital interface and an internal ±0.5%-initial accuracy +2.5 V reference. Operating from +2.7 V to +3.6 V supplies, it consumes approximately 3 mW when converting at 187.5 ksps. One or two analog inputs each have an input range from 0 V to VREF or 0 V to VDD. Four user-programmable, low-power operating modes including auto standby and auto power down with a shutdown-mode supply current of 1 μA (max) and a -40°C to +85°C operating temperature range. The device is suitable as stand-alone 12 bit ADC in low-power, industrial, process control and data-acquisition applications. Some portable and fixed-form-factor applications include optical sensors, touch panels, personal digital assistants, programmable logic controllers and medical instrumentation. Available immediately, the TS7001 12 bit ADC is priced at $1.15 each/1,000.
