ADC12L063中文资料12 位、62MSPS 模数转换器 (ADC)数据手册TI规格书

描述 Description

The ADC12L063 is a monolithic CMOS analog-to-digital converter capable of converting analog input signals into 12-bit digital words at 62 Megasamples per second (MSPS), minimum. This converter uses a differential, pipelined architecture with digital error correction and an on-chip sample-and-hold circuit to minimize die size and power consumption while providing excellent dynamic performance. Operating on a single 3.3V power supply, this device consumes just 354 mW at 62 MSPS, including the reference current. The Power Down feature reduces power consumption to just 50 mW.The differential inputs provide a full scale input swing equal to ±VREF with the possibility of a single-ended input. Full use of the differential input is recommended for optimum performance. For ease of use, the buffered, high impedance, single-ended reference input is converted on-chip to a differential reference for use by the processing circuitry. Output data format is 12-bit offset binary.This device is available in the 32-lead LQFP package and will operate over the industrial temperature range of −40°C to +85°C.

简介

ADC12L063属于集成电路（IC）的模数转换器（ADC）。由TI制造生产的ADC12L063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。
