MAX127ACAI+

多量程, 12位数据采集系统, 2线串行接口, 4.75 V至5.25 V, SSOP-28

The from Products is a multirange, +5V, 12bit data acquisition system 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 8 analogue input channels that are independently software programmable for a variety of ranges such as ±10V, ±5V, 0 to +10V and 0 to +5V. This range switching increases effective dynamic range to 14bits and provides the flexibility to interface 4mA to 20mA, ±12V and ±15V powered sensors directly to a single +5V system. The converter is fault protected to ±16.5V and a fault condition on any channel will not affect conversion result of selected channel. A hardware shutdown active-low input and two software programmable power-down modes are provided for low current shutdown between conversions. In standby mode, reference buffer remains active, eliminating start-up delays.
