MAX1225ETC-T中文资料美信数据手册PDF规格书

General Description

The MAX1224/MAX1225 low-power, high-speed, serial-output, 12-bit, analog-to-digital converters (ADCs) operate at up to 1.5Msps. These devices feature true-differential inputs, offering better noise immunity, distortion improvements, and a wider dynamic range over single-ended inputs. A standard SPI™/QSPI™/MICROWIRE™ interface provides the clock necessary for conversion. These devices easily interface with standard digital signal processor (DSP) synchronous serial interfaces.
