DESCRIPTION
A 4-wire serial interface connects directly to SPI™/Microwire™ devices without external logic, and a serial strobe output allows direct connection to TMS320-family digital signal processors. The serial interface operates at up to 2MHz. The MAX1204 features an internal 4.096V reference and a reference-buffer amplifier that simplifies gain trim. It also has a VL pin that supplies power to the digital outputs. Output logic levels (3V, 3.3V, or 5V) are determined by the value of the voltage applied to this pin. A hard-wired SHDN pin and two software-selectable power-down modes are provided. Accessing the serial interface automatically powers up the device. A quick turn-on time allows the MAX1204 to be shut down between conversions, enabling the user to optimize supply currents. By customizing power-down between conversions, supply current can drop below 10µA at reduced sampling rates. The MAX1204 is available in 20-pin SSOP and DIP packages, and is specified for the commercial,...
