General Description
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)
with a 25MHz SPI-/QSPI-/MICROWIRE-compatible
serial interface. The ADC is available in 8/12/16 input-
channel versions. The octal DAC outputs settle within
2.0s, 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 ±1°C 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 (4nVs) and low digital feedthrough (0.5nVs) 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 22A at
1ksps throughput, and under 0.2A in the shutdown
mode. The MAX1057/MAX1058 feature 12 GPIOs, while
the MAX1020 offers four GPIOs that can be configured as
inputs or outputs.
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
-40°C to +85°C temperature range.
