MAX152EAP+T

The MAX152EAP+T is a +3V, 8bit analogue to digital converter (ADC) with 1μA power down mode in 20 pin SSOP package. This high speed, microprocessor (μP) compatible ADC uses a half flash technique to achieve 1.8μs conversion time and digitizes at a rate of 400Ksps. It operates with single +3V or dual ±3V supplies and accepts either unipolar or bipolar inputs. A active-low power-down pin reduces current consumption to typical value of 1μA. The device returns from power-down and acquires an input signal in less than 900ns providing large reductions in supply current in applications with burst mode input signals. The μP interface appears as a memory location or I/O port that requires no external interface logic. The data outputs use latched, three state buffered circuitry for direct connection to μP data bus or system input port. The ADC's input/reference arrangement enables ratiometric operation. It is used in burst mode data acquisition, telecommunications and high speed servo loops.
