The Microchip Technology Inc. MCP3302/04 13-bit A/D converters feature full differential inputs and low power consumption in a small package that is ideal for battery powered systems and remote data acquisition applications.
The MCP3302 is programmable to provide two differential input pairs or four single ended inputs. The MCP3304 is programmable and provides four differential input pairs or eight single ended inputs.

Incorporating a successive approximation architecture with on-board sample and hold circuitry, these 13-bit A/D converters are specified to have ±1 LSB Differential Nonlinearity (DNL); ±1 LSB Integral Nonlinearity (INL) for B-grade and ±2 LSB for C-grade devices. The industry-standard SPI™ serial interface enables 13-bit A/D converter capability to be added to any PICmicro® microcontroller.

The MCP3302/04 devices feature low current design that permits operation with typical standby and active currents of only 50 nA and 300 A, respectively. The devices operate over a broad voltage range of 2.7V to 5.5V and are capable of conversion rates of up to 100 ksps. The reference voltage of MCP3302/04 can be varied from 400 mV to 5V, yielding input-referred resolution between 98 V and 1.22 mV.

The MCP3302 is available in 14-pin PDIP, 150 mil SOIC and TSSOP packages. The MCP3304 is available in 16-pin PDIP and 150 mil SOIC packages. The full differential inputs of these devices enable a wide variety of signals to be used in applications such as remote data acquisition, portable instrumentation and battery operated applications.
