MAX1091中文资料250ksps、+3V、8/4通道、10位ADC，带有+2.5V电压基准及并行接口数据手册ADI规格书

描述 Description

The MAX1091/MAX1093 low-power, 10-bit analog-to-digital converters (ADCs) feature a successive-approximation ADC, automatic power-down, fast wake-up (2µs), an on-chip clock, +2.5V internal reference, and a high-speed, byte-wide parallel interface. They operate with a single +3V analog supply and feature a VLOGIC pin that allows them to interface directly with a +1.8V to +3.6V digital supply.
Power consumption is only 5.7mW (VDD = VLOGIC) at the maximum sampling rate of 250ksps. Two software-selectable power-down modes enable the MAX1091/MAX1093 to be shut down between conversions; accessing the parallel interface returns them to normal operation. Powering down between conversions can cut supply current to under 10µA at reduced sampling rates.
Both devices offer software-configurable analog inputs for unipolar/bipolar and single-ended/pseudo-differential operation. In single-ended mode, the MAX1091 has eight input channels and the MAX1093 has four input channels (four and two input channels, respectively, when in pseudo-differential mode).
Excellent dynamic performance and low power, combined with ease of use and small package size, make these converters ideal for battery-powered and data-acquisition applications or for other circuits with demanding power consumption and space requirements.
The MAX1091/MAX1093 tri-states active-low INT when active-low CS goes high. Refer to MAX1061/MAX1063 if tri-stating active-low INT is not desired.
The MAX1091 is available in a 28-pin QSOP package, while the MAX1093 is available in a 24-pin QSOP. For pin-compatible +5V, 10-bit versions, refer to the MAX1090/MAX1092 data sheet.

简介

MAX1091属于集成电路（IC）的模数转换器（ADC）。由制造生产的MAX1091模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。
