MAX1082A, MAX1082B




The MAX1082/MAX1083 10-bit analog-to-digital converters (ADCs) combine a 4-channel analog-input multiplexer, high-bandwidth track/hold (T/H), and serial interface with high conversion speed and low power consumption. The MAX1082 operates from a single +4.5V to +5.5V supply; the MAX1083 operates from a single +2.7V to +3.6V supply. Both devices' analog inputs are software configurable for unipolar/bipolar and single-ended/pseudo-differential operation.

The 4-wire serial interface connects directly to SPI/QSPI™ and MICROWIRE® devices without external logic. A serial strobe output allows direct connection to TMS320-family digital signal processors. The MAX1082/ MAX1083 use an external serial-interface clock to perform successive-approximation analog-to-digital conversions. The devices feature an internal +2.5V reference and a reference-buffer amplifier with a ±1.5% voltage-adjustment range. An external reference with a 1V to VDD range may also be used.

The MAX1082/MAX1083 provide a hard-wired active-low SHDN pin and four software-selectable power modes (normal operation, reduced power (REDP), fast power-down (FASTPD), and full power-down (FULLPD)). These devices can be programmed to shut down automatically at the end of a conversion or to operate with reduced power. When using the power-down modes, accessing the serial interface automatically powers up the devices, and the quick turn-on time allows them to be shut down between all conversions.

The MAX1082/MAX1083 are available in 16-pin TSSOP packages.
