General Description

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 Differen-

tial 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 PIC

microcontroller.

The MCP3302/04 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 devices enable a

wide variety of signals to be used in applications such

as remote data acquisition, portable instrumentation,

and battery operated applications.
