MCP3204/3208

2.7V 4-Channel/8-Channel 12-Bit A/D Converters

with SPI Serial Interface

Features

Description

• 12-bit resolution

The Microchip Technology Inc. MCP3204/3208

devices are successive approximation 12-bit Analog-

to-Digital (A/D) Converters with on-board sample and

hold circuitry. The MCP3204 is programmable to

provide two pseudo-differential input pairs or four

single-ended inputs. The MCP3208 is programmable

to provide four pseudo-differential input pairs or eight

single-ended inputs. Differential Nonlinearity (DNL) is

specified at ±1 LSB, while Integral Nonlinearity (INL) is

offered in ±1 LSB (MCP3204/3208-B) and ±2 LSB

(MCP3204/3208-C) versions.

• ± 1 LSB max DNL

• ± 1 LSB max INL (MCP3204/3208-B)

• ± 2 LSB max INL (MCP3204/3208-C)

• 4 (MCP3204) or 8 (MCP3208) input channels

• Analog inputs programmable as single-ended or

pseudo-differential pairs

• On-chip sample and hold

• SPI serial interface (modes 0,0 and 1,1)

• Single supply operation: 2.7V - 5.5V

• 100 ksps max. sampling rate at V_DD= 5V

• 50 ksps max. sampling rate at V_DD= 2.7V

• Low power CMOS technology:

Communication with the devices is accomplished using

a simple serial interface compatible with the SPI

protocol. The devices are capable of conversion rates

of up to 100 ksps. The MCP3204/3208 devices operate

over a broad voltage range (2.7V - 5.5V). Low current

design permits operation with typical standby and

active currents of only 500 nA and 320 µA,

respectively. The MCP3204 is offered in 14-pin PDIP,

150 mil SOIC and TSSOP packages. The MCP3208 is

offered in 16-pin PDIP and SOIC packages.

- 500 nA typical standby current, 2 µA max.

- 400 µA max. active current at 5V

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

• Available in PDIP, SOIC and TSSOP packages
