MAX1111MJE中文资料美信数据手册PDF规格书

General Description

The MAX1110/MAX1111 are low-power, 8-bit, 8-channel analog-to-digital converters (ADCs) that feature an internal track/hold, voltage reference, clock, and serial interface. They operate from a single +2.7V to +5.5V supply and consume only 85µA while sampling at rates up to 50ksps. The MAX1110’s 8 analog inputs and the MAX1111’s 4 analog inputs are software-configurable, allowing unipolar/bipolar and single-ended/differential operation.
