MAX1340BETX-MAX1342BETX
4.096 V, 12-bit, multichannel ADC/DAC with FIFO, temperature sensing, and GPIO port
General DescriptionThe MAX1340–MAX1343/MAX1346–MAX1349 integrate a
multichannel, 12-bit, analog-to-digital converter (ADC)
and a quad, 12-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 seri-
al interface. The ADC is available in a 4 or an 8 input-
channel version. The four DAC outputs settle within 2.0µs,
and the ADC has a 300ksps 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 DAC allow the use of an internal reference,
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 consumption and proces-
sor requirements. The low glitch energy (4nV•s) and low
digital feedthrough (0.5nV•s) of the integrated quad
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 (MAX1341/MAX1343/MAX1347/
MAX1349) and from +4.5V to +5.5V (MAX1340/MAX1342/
MAX1346/MAX1348). The devices consume 2.5mA at
300ksps throughput, only 22µA at 1ksps throughput, and
under 0.2µA in the shutdown mode. The MAX1342/
MAX1343/MAX1348/MAX1349 offer four GPIOs that can
be configured as inputs or outputs.
The MAX1340–MAX1343/MAX1346–MAX1349 are avail-
able in 36-pin thin QFN packages. All devices are speci-
fied over the -40°C to +85°C temperature range.
