I. Device Description

A. General

The MAX1040/MAX1042/MAX1046/MAX1048 integrate a multichannel, 10-bit, analog-to-digital converter (ADC) and a quad, 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(tm)-/QSPI(tm)-/MICROWIRE(tm)-compatible serial interface. The ADC is available in a four or an eight 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) 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(tm) allow users to minimize both power consumption and processor

requirements. The low glitch energy (4nVs) and low digital feedthrough (0.5nVs) 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. These

devices consume 2.5mA at 225ksps throughput, only 22µA at 1ksps throughput, and under 0.2µA in the shutdown mode. The MAX1042/MAX1048

offer four GPIOs that can be configured as inputs or outputs. The MAX1040/MAX1042/MAX1046/MAX1048 are available in 36-pin thin QFN

packages. All devices are specified over the -40°C to +85°C temperature range.
