The MAX127/MAX128 are multirange, 12-bit data acquisition systems (DAS) that require only a single +5V supply for operation, yet accept signals at their analog inputs that may span above the power-supply rail and below ground. These systems provide eight analog input channels that are independently software programmable for a variety of ranges: ±10V, ±5V, 0 to +10V, 0 to +5V for the MAX127; and ±VREF, ±VREF/2, 0 to +VREF , 0 to +VREF/2 for the MAX128. This range switching increases the effective dynamic range to 14 bits and provides the flexibility to interface 420mA, ±12V, and ±15V-powered sensors directly to a single +5V system. In addition, these converters are fault pro-tected to ±16.5V; a fault condition on any channel will not affect the conversion result of the selected channel. Other features include a 5MHz bandwidth track/hold, an 8ksps throughput rate, and the option of an internal 4.096V or external reference.
The MAX127/MAX128 feature a 2-wire, I2C-compatible serial interface that allows communication among multi-ple devices using SDA and SCL lines.
A hardware shutdown input (SHDN</a>) and two software-programmable power-down modes (standby and full power-down) are provided for low-current shutdown between conversions. In standby mode, the reference- buffer remains active, eliminating start-up delays.
The MAX127/MAX128 are available in 24-pin DIP or space-saving 28-pin SSOP packages.
