10-Bit, Multichannel ADCs/DACs with FIFO,

Temperature Sensing, and GPIO Ports

27/MAX1058

General Description

Features

The MAX1020/MAX1022/MAX1057/MAX1058 integrate a

multichannel, 10-bit, analog-to-digital converter (ADC)

and an octal, 10-bit, digital-to-analog converter (DAC) in a

single IC. These devices also include a temperature sen-

sor and configurable general-purpose I/O ports (GPIOs)

serial interface. The ADC is available in 8/12/16 input-

channel versions. The octal DAC outputs settle within

2.0µs, and the ADC has a 225ksps conversion rate.

All devices include an internal reference (2.5V or 4.096V)

providing a well-regulated, low-noise reference for both

the ADC and DAC. Programmable reference modes for

the ADC and the DAC allow the use of an internal refer-

ence, an external reference, or a combination of both.

Features such as an internal 1ꢀC accurate temperature

sensor, FIFO, scan modes, programmable internal

or external clock modes, data averaging, and

AutoShutdown™ allow users to minimize both power con-

sumption and processor requirements. The low glitch

energy (4nV•s) and low digital feedthrough (0.5nV•s) of

the integrated octal DACs make these devices ideal for

digital control of fast-response closed-loop systems.

o On-Chip Channel-Scan Mode and ꢂnternal

The devices are guaranteed to operate with a supply volt-

age from +2.7V to +3.6V (MAX1057) and from +4.75V to

+5.25V (MAX1020/MAX1022/MAX1058). The devices

consume 2.5mA at 225ksps throughput, only 22µA at

1ksps throughput, and under 0.2µA in the shutdown

mode. The MAX1057/MAX1058 feature 12 GPIOs, while

the MAX1020 offers four GPIOs that can be configured as

inputs or outputs.

Data-Averaging Features

o Analog Single-Supply Operation

+2ꢀ7V to +3ꢀ6V or +4ꢀ75V to +5ꢀ25V

o Digital Supply: 2ꢀ7V to V

o 25MHz, SPꢂ/QSPꢂ/MꢂCROWꢂRE Serial ꢂnterface

o AutoShutdown Between Conversions

The MAX1057/MAX1058 are available in 48-pin thin QFN

packages. The MAX1020/MAX1022 are available in 36-

pin thin QFN packages. All devices are specified over the

-40ꢀC to +85ꢀC temperature range.

o ꢁow-Power ADC

2ꢀ5mA at 225ksps

22µA at 1ksps

0ꢀ2µA at Shutdown

o ꢁow-Power DAC: 1ꢀ5mA
