MAX1280, MAX1280B, MAX1281, MAX1281B 400ksps/300ksps, Single-Supply, Low-Power, 8-Channel, Serial 12-Bit ADCs With Internal Reference

The MAX1280 MAX1281 12-bit ADCs combine an 8-channel analog-input multiplexer, high-bandwidth track/hold, and serial Interface with high conversion speed and low power consumption. The MAX1280 operates from a single +4.5V to +5.5V supply; the MAX1281 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"/MICROWIRE" devices without external Logic A serial strobe output allows direct connection to TMS320-family digital signal processors. The MAX1280 MAX1281 use an external serial-interface Clock to perform successive-approximation Analog-to-digital conversions. Both parts 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 MAX1280 MAX1281 provide a hard-wired active-low SHDN pin and four software-selectable power modes (normal operation, reduced power, fast power-down, and full power-down). 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 powered down between all conversions. This technique CAN cut supply current to under 100A at reduced sampling rates.
The MAX1280 MAX1281 are available in 20-pin TSSOP packages. These devices are higher-speed versions of the MAX146 MAX147 (for more information, see the respective data sheet).
