2.7V 10-Bit A/D Converter With SPI? Serial Interface

MCP3001 The Microchip Technology Inc. MCP3001 is a succes- sive approximation 10-bit A/D converter (ADC) with on- board Sample and Hold circuitry. The device provides a single pseudo-differential input. Differential Nonlinear- ity (DNL) and Integral Nonlinearity (INL) are both spec- ified at 1 LSB max. Communication with the device i done using a simple serial Interface compatible with the SPI protocol. The device is capable of sample rates up to 200 ksps at a Clock rate of 2.8 MHz. The MCP3001 operates over a broad voltage range (2.7V - 5.5V). Low current design permits operation with a typical standby current of only 5 nA and a typical active current of 400 A. The device is offered in 8-pin PDIP, MSOP TSSOP and 150 mil SOIC packages. By Microchip Technology Inc.
