MAX1203BEPP集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

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.
