General Description

The MCP3302/04 13-bit A/D converter features 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 user-programmable to provide two

differential input pairs or four single-ended inputs.

The MCP3304 is also user-programmable to configure

into 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 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

device is capable of conversion rates of up to 100 ksps

with tested specifications over a 4.5V to 5.5V supply

range. 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.
