MAX1220/MAX1257/MAX1258

General Description

Benefits and Features

The MAX1220/MAX1257/MAX1258 is a highly integrat-

ed system monitoring and control solution which

includes a 16-channel (MAX1257/MAX1258) or 8-ch

(MAX1220) 12-bit Analog to Digital Converter (ADC),

twelve 12-bit Digital to Analog Converters (DACs), an

internal reference, an internal temp sensor, a 4-bit

(MAX1220) or 12-bit (MAX1257/MAX1258) GPIO port,

and a 25MHz SPI-/QSPI™-/MICROWIRE^®- compatible

serial interface.

• Reduce Parts Count and Board Space with Fully

Integrated System Monitor and Controller

• Monitors 8 (MAX1220) or 16 Voltages

(MAX1257/MAX1258) Using 12-Bit, 225ksps ADC

• Controls 8 Output Voltage Level with 12-Bit, Octal,

2µs Settling DAC with Ultra-Low Glitch Energy

(4n x VS)

• Measures Temperature with Internal 1°C

Accurate Temperature Sensor

• Options for Using Either Internal 2.5V (MAX1257)

The MAX1220 is available in a 36-pin TQFN package.

The MAX1257/MAX1258 are available in 48-pin TQFN

package. All devices are specified over the -40°C to

+85°C temperature range.
