Description

The Microchip Technology Inc. MCP330413-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 pairsor eight single ended inputs.

Incorporating a successive approximation architecture with on-board sample and hold circuitry, these 13-bit A/D converters MCP3304 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 of MCP3304 enables 13-bit A/D converter capability to be added to any PICmicro® microcontroller.

The MCP3304 devices feature low current design that permits operation with typical standby and active currents of only 50 nA and 300 µA, 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 can be varied from 400 mV to 5V, yielding input-referred resolution between 98 µV 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 MCP3304 enable a wide variety of signals to be used in applications such as remote data acquisition, portable instrumentation and battery operated applications.
