General Description
The MAX1202/MAX1203 are 12-bit data-acquisition systems specifically designed for use in applications with mixed +5V (analog) and +3V (digital) supply voltages. They operate with a single +5V analog supply or dual ±5V analog supplies, and combine an 8-channel multiplexer, high-bandwidth track/hold, and serial interface with high conversion speed and low power consumption.

FEATUREs
♦ 8-Channel Single-Ended or 4-Channel Differential Inputs
♦ Operates from Single +5V or Dual ±5V Supplies
♦ User-Adjustable Output Logic Levels (2.7V to 5.25V)
♦ Low Power: 1.5mA (operating mode) 2µA (power-down mode)
♦ Internal Track/Hold, 133kHz Sampling Rate
♦ Internal 4.096V Reference (MAX1202)
♦ SPI/MICROWIRE/TMS320-Compatible 4-Wire Serial Interface
♦ Software-Configurable Unipolar/Bipolar Inputs
♦ 20-Pin DIP/SSOP
