12-bit, 125-ksps ADC targets low-power, industrial, process control apps
Touchstone Semiconductor announced the immediate availability of the TSA7887, a two-channel, 12-bit, 125-ksps analog-to-digital converter (ADC) that can be used as a drop-in replacement for the Analog Devices AD7887. Priced at $1.25 in 1,000-piece quantities, the new IC offers 2.6-mW power consumption at 125 ksps while operating from a single +2.7 V to +5.25 V; four user-programmable, low-power operating modes including auto standby and auto power down; two INL options: TSA7887B with ±1 LSB INL and TSA7887A with ±2 LSB INL; -40°C to +125°C operating temperature; one or two analog inputs each with an input range from 0 V to VREF or 0 V to VDD; and an integrated 2.5 V reference. The TSA7887 stand-alone 12-bit ADC is suitable in low-power, industrial, process control and data-acquisition applications. Some portable and fixed-form-factor applications for the TSA7887 include: optical sensors, touch panels, personal digital assistants, programmable logic controllers, and medical instrumentation.
