MAXIM INTEGRATED / ANALOG DEVICES MAX128BCAI+ Datasheet & Stock

The MAX128BCAI+ is a multirange, +5V, 12bit data acquisition system (DAS) with 2-wire serial interface in 28 pin SSOP package. Device operates at single supply, yet accepts signals at its analogue inputs that may span above the power supply rail and below ground. It provides eight analogue input channels that are independently software programmable for a variety of ranges such as ±VREF, ±VREF/2, 0 to +VREF and 0 to +VREF/2. This range switching increases effective dynamic range to 14bits & provides flexibility to interface 4mA-20mA, ±12V & ±15V powered sensors directly to a single +5V system. The converter is fault protected to ±16.5V & a fault condition on any channel will not affect the conversion result of selected channel. A hardware shutdown input (SHDN-complementary) and two software programmable power-down modes (standby & full power-down) are provided for low current shutdown between conversions. In standby mode, the reference buffer remains active, eliminating start-up delays.
