Photograph
Product Details
The MAX192 is a 10-bit analog to digital converter with
8-channel multiplexer, fast track/hold and a high-speed serial interface.
The analog inputs for the MAX192 are software configurable for single ended or differential inputs.
The converter operates from a single +5V power supply and includes an internal 4.096V voltage reference.
The 4-wire serial interface can connect directly to SPI, QSPI and Microwire devices.
Features
- 8-Channel Single-Ended or 4-Channel Differential Inputs
- Single +5V Operation
- Low Power: 1.5mA (operating) 2µA (power-down)
- Internal Track/Hold, 133kHz Sampling Rate
- Internal 4.096V Reference
- 4-Wire Serial Interface is Compatible with SPI, QSPI and Microwire
- Pin-Compatible 12-Bit Upgrade (MAX186/MAX188)
