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.

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.
