MCP3201 2.7V 12-Bit A/D Converter with SPI Serial Interface Features Description 12-Bit Resolution The Microchip Technology Inc. MCP3201 device is a successive approximation 12-bit Analog-to-Digital 1 LSB max DNL (A/D) Converter with on-board sample and hold 1 LSB max INL (MCP3201-B) circuitry. The device provides a single pseudo-differen- 2 LSB max INL (MCP3201-C) tial input. Differential Nonlinearity (DNL) is specified at On-chip Sample and Hold 1 LSB, and Integral Nonlinearity (INL) is offered in SPI Serial Interface (modes 0,0 and 1,1) 1LSB (MCP3201-B) and 2LSB (MCP3201-C) Single Supply Operation: 2.7V - 5.5V versions. Communication with the device is done using a simple serial interface compatible with the SPI 100 ksps Maximum Sampling Rate at V = 5V DD protocol. The device is capable of sample rates of up to 50 ksps Maximum Sampling Rate at V = 2.7V DD 100 ksps at a clock rate of 1.6 MHz. The MCP3201 Low-Power CMOS Technology device operates over a broad voltage range (2.7V- 500 nA Typical Standby Current, 2 A Maximum 5.5V). Low-current design permits operation with 400 A Maximum Active Current at 5V typical standby and active currents of only 500 nA and 300 A, respectively. The device is offered in 8-pin Industrial Temp Range: -40C to +85C MSOP, PDIP, TSSOP and 150 mil SOIC packages. 8-pin MSOP, PDIP, SOIC and TSSOP Packages Package Types Applications Sensor Interface MSOP, PDIP, SOIC, TSSOP Process Control Data Acquisition V 1 8 V REF DD Battery Operated Systems IN+ 2 7 CLK Functional Block Diagram IN 3 6 D OUT V 4 5 CS/SHDN SS V V SS DD V REF DAC Comparator 12-Bit SAR IN+ Sample and Hold IN- Shift Control Logic Register CS/SHDN CLK D OUT 1998-2011 Microchip Technology Inc.
