The MAX1080/MAX1081 10-bit analog-to-digital converters (ADCs) combine an 8-channel analog-input multiplexer, high-bandwidth track/hold (T/H), and serial interface with high conversion speed and low power consumption. The MAX1080 operates from a single +4.5V to +5.5V supply; the MAX1081 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 MAX1080/MAX1081 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 VDD1 range may also be used.
The MAX1080/MAX1081 provide a hard-wired activel-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 automatically shut down 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. This technique can cut supply current below 100mA at lower sampling rates.
The MAX1080/MAX1081 are available in a 20-pin TSSOP package. These devices are higher-speed versions of the MAX148/MAX149. For more information, refer to the respective data sheet.
