The MAX153EWP+ is a 1Msps, µP compatible, 8bit analogue to digital converter (ADC) with 1µA power-down in 20 pin WSOIC package. This ADC uses a half-flash technique to achieve a 660ns conversion time and digitizes at a rate of 1Msps. It operates with single +5V or dual ±5V supplies and accepts either unipolar or bipolar inputs. A POWERDN (complementary, 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. It is dynamically tested and its µP interface appears as 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.
