General Description
The MAX1021/MAX1043 integrate a multichannel, 10-bit,
analog-to-digital converter (ADC) and a 10-bit, digital-to-
analog converter (DAC) in a single IC. The devices also
include a temperature sensor and configurable general-
purpose I/O ports (GPIOs) with a 25MHz SPI-/QSPI-/
MICROWIRE-compatible serial interface. The ADC is
available in an eight input-channel version. The DAC out-
puts settle within 2.0s, and the ADC has a 225ksps con-
version rate.
All devices include an internal reference (2.5V) to provide
a well-regulated, low-noise reference for both the ADC
and DAC. Programmable reference modes for the ADC
and DAC allow the use of an internal reference, an exter-
nal 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 consumption and processor
requirements. The low glitch energy (4nVs) and low digi-
tal feedthrough (0.5nVs) of the integrated 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 +5.25V. They consume 2.5mA at
225ksps throughput, only 22A at 1ksps throughput, and
under 0.2A in the shutdown mode. The MAX1021/
MAX1043 offer four GPIOs that can be configured as
inputs or outputs.
The MAX1021/MAX1043 are available in 36-pin thin QFN
packages. These devices are specified over the -40°C to
+85°C temperature range.
