MAX1181集成電路（IC）的觸摸屏控制器規(guī)格書PDF中文資料

General Description

The MAX1181 is a 3V, dual 10-bit, analog-to-digital converter (ADC) featuring fully-differential wideband track-and-hold (T/H) inputs, driving two pipelined, nine stage ADCs. The MAX1181 is optimized for low-power, high-dynamic performance applications in imaging, instrumentation, and digital communication applications. The MAX1181 operates from a single 2.7V to 3.6V supply, consuming only 246mW, while delivering a typical signal-to-noise ratio (SNR) of 59dB at an input frequency of 20MHz and a sampling rate of 80Msps. The T/H driven input stages incorporate 400MHz (-3dB) input amplifiers. The converters may also be operated with single-ended inputs. In addition to low operating power, the MAX1181 features a 2.8mA sleep mode, as well as a 1μA power-down mode to conserve power during idle periods.
