Monolithic Power Systems (MPS) MDC97476/7/8 Analog-to-Digital Converters (ADCs)
Monolithic Power Systems (MPS) MDC97476/7/8 Analog-to-Digital Converters (ADCs) are 12-bit, 10-bit, and 8-bit, respectively, high-speed, low-power successive-approximation ADCs. The parts operate from a single 3V to 3.6V power supply with a conversion rate up to 1MSPS.
The MDC97476/7/8 uses a three-wire SPI-compatible serial digital interface for chip control and data output. The serial clock determines the sampling rate, and a chip-select pin controls the conversion process and data acquisition.
The MPS MDC97476/7/8 use the power supply as the reference, and power consumption is as low as 4.9mW at a 1MSPS conversion rate with a 3.3V power supply. The parts are available in a 6-pin TSOT-23 package, with an operating temperature range of -40°C to +85°C.
