Maxim MAX1531ETJ/V+

Контроллер, TFT ЖК-дисплей4,5 В ~ 28 В

Overview

The MAX1531ETJ high-speed, microprocessor (μP)-compatible, 8-bit analog-to-digital converter (ADC) uses a half-flash technique to achieve a 660ns conversion time, and digitizes at a rate of 1M samples per second (Msps). It operates with single +5V or dual ±5V supplies and accepts either unipolar or bipolar inputs. An active-low POWERDN (power-down) pin reduces current consumption to a typical value of 1μA (with 5V supply). The part returns from power-down to normal operating mode in less than 200ns, providing large reductions in supply current in applications with burst-mode input signals.

The MAX1531ETJ is DC and dynamically tested. Its μP interface appears as a memory location or input/output port that requires no external interface logic. The data outputs use latched, three-state buffered circuitry for direct connection to a μP data bus or system input port. The ADC’s input/reference arrangement enables ratiometric operation.
