The MAX153CPP+ is a 1Msps, μP compatible, 8bit analogue to digital converter (ADC) with 1μA power-down in 20 pin DIP 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.
