MCP3002

MCP3002 Features 2.7V Dual Channel 10-Bit A/D Converter with SPI Serial Interface Description 10-bit resolution ±1 LSB maximum DNL ±1 LSB maximum INL Analog inputs programmable as single-ended or pseudo-differential pairs On-chip sample and hold SPI serial interface (modes 0,0 and 1,1) Single supply operation: 2.7V - 5.5V 200 ksps max sampling rate at VDD = 5V 75 ksps max sampling rate at VDD = 2.7V Low power CMOS technology: - 5 nA typical standby current, 2 µA maximum - 550 µA maximum active current at 5V Industrial temperature range: -40°C to +85°C 8-pin MSOP, PDIP, SOIC and TSSOP packages Applications Sensor Interface Process Control Data Acquisition Battery Operated Systems Functional Block Diagram VDD VSS The MCP3002 is a successive approximation 10-bit analog-to-digital (A/D) converter with on-board sample and hold circuitry. The MCP3002 is programmable to provide a single pseudo-differential input pair or dual single-ended inputs. Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) are both specified at ±1 LSB. Communication with the device is done using a simple serial interface compatible with the SPI protocol. The device is capable of conversion rates of up to 200 ksps at 5V and 75 ksps at 2.7V. The MCP3002 operates over a broad voltage range, 2.7V to 5.5V. Low-current design permits operation with a typical standby current of 5 nA and a typical active current of 375 µA. The MCP3002 is offered in 8-pin MSOP, PDIP, TSS...
