MAX1438BETK+集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

General Description

The MAX1438B octal, 12-bit analog-to-digital converter (ADC) features fully differential inputs, a pipelined architecture, and digital error correction incorporating a fully differential signal path. This ADC is optimized for low-power and high-dynamic performance in medical imaging instrumentation and digital communications applications. The MAX1438B operates from a 1.8V single supply and consumes only 913mW (114mW per channel) while delivering a 69.9dB (typ) signal-to-noise ratio (SNR) at a 5.3MHz input frequency. In addition to low operating power, the MAX1438B features a low power standby mode for idle periods.
