The TSA7887 is a two-channel, 12-bit, 125-ksamples/s A/D converter (ADC) that can be used as a drop-in replacement for the Analog Devices AD7887. The device offers a 2.6-mW power consumption at 125 ksamples/s while operating from a single +2.7 to +5.25 V.
Features include an integrated 2.5-V reference and four user-programmable, low-power operating modes including auto standby and auto power down. The part provides one or two analog inputs each with an input range from 0V to VREF or 0V to VDD.
Housed in 8-pin SOIC and MSOP packages, the part is fully specified from -40° to +125°C. Two INL options: TSA7887B with ±1LSB INL and TSA7887A with ±2LSB INL. ($1.25 ea/1,000 — available now)
