説明
The MAX40110/MAX40111 offer a unique combination of high speed, precision, low noise, and low-voltage operation, making them ideally suited for a large number of signal processing functions including filtering and amplification of signals in portable and industrial equipment.
The MAX40110/MAX40111s' rail-to-rail input/outputs and low noise guarantee maximum dynamic range in demanding applications such as 12- to 14-bit SAR ADC drivers. Unlike traditional rail-to-rail input structures, input crossover distortion is absent due to an optimized input stage with an ultra-quiet charge pump. The input offset voltage is as low as 30µV due to the auto-calibration performed on power-up. The devices also include a fast-power-on shutdown mode for further power savings.
The MAX40110/MAX40111 operate from a supply range of 1.8V to 5.5V over the -40°C to +125°C extended operating temperature range and consume only 750μA (typ) supply current. The MAX40110 is offered in an ultra-thin 6-µDFN package, and the MAX40111 is available in a tiny 6-bump wafer-level-package (WLP) with a 0.4mm pitch.
The MAX40110/MAX40111 are an extension of the MAX44259/60/61/63 and MAX44290 families with a reduced power up time of less than 1ms.
