MCP3302/04

13-Bit Differential Input, Low Power A/D Converter

with SPI™ Serial Interface

Features

General Description

• Full Differential Inputs

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 applica-

tions. The MCP3302 is programmable to provide two

differential input pairs or four single ended inputs. The

MCP3304 is programmable and provides four differen-

tial input pairs or eight single ended inputs.

• MCP3302: 2 Differential or 4 Single ended Inputs

• MCP3304: 4 Differential or 8 Single ended Inputs

• ±1 LSB max DNL

• ±1 LSB max INL (MCP3302/04-B)

• ±2 LSB max INL (MCP3302/04-C)

• Single supply operation: 2.7V to 5.5V

• 100 ksps sampling rate with 5V supply voltage

• 50 ksps sampling rate with 2.7V supply voltage

• 50 nA typical standby current, 1 µA max

• 450 µA max active current at 5V

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

• Industrial temp range: -40°C to +85°C

• 14 and 16-pin PDIP, SOIC and TSSOP packages

A/D converter capability to be added to any PICmicro

microcontroller.

• MXDEV Evaluation kit available

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 avail-

able 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.
