General Description

The MAX1340/MAX1342/MAX1346/MAX1348 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 225ksps conversion rate.

All devices include an internal reference (4.096V) provid-

ing 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

voltage from +4.75V to +5.25V The devices consume

2.5mA at 225ksps throughput, only 22µA at 1ksps

throughput, and under 0.2µA in the shutdown mode. The

MAX1342/MAX1348 offer four GPIOs that can be config-

ured as inputs or outputs.

The MAX1340/MAX1342/MAX1346/MAX1348 are avail-

able in 36-pin thin QFN packages. All devices are speci-

fied over the -40°C to +85°C temperature range.
