General Description

The MAX152 high-speed, microprocessor (μP)-compatible, 8-bit analog-to-digital converter (ADC) uses a half-flash technique to achieve a 1.8μs conversion time, and digitizes at a rate of 400k samples per second (ksps). It operates with single +3V or dual ±3V supplies and accepts either unipolar or bipolar inputs. A –P—O—W—E—R—D—O—W—N– pin reduces current consumption to a typical value of 1μA. The part returns from powerdown and acquires an input signal in less than 900ns, providing large reductions in supply current in applications with burst-mode input signals.
