Product Details
The MAX186BCWP is an 8-channel, 12-bit analog to digital converter with
high bandwidth track/hold, high conversion speed, ultra-low power consumption and a serial interface.
The converter operates from a single +5V power supply or dual ±5V supplies.
The analog inputs for the MAX186 are software configurable for unipolar/bipolar and single-ended/differential operation.
The MAX186 also includes an internal 4.096V voltage reference and has two power-down modes, which reduce power consumption to
under 10µA.
Features
- 8-Channel Single-Ended or 4-Channel Differential Inputs
- Single +5V or ±5V Operation
- Low Power: 1.5mA (operating mode) 2µA (power-down mode)
- Internal Track/Hold, 133kHz Sampling Rate
- Internal 4.096V Reference
- SPI-, QSPI-, Microwire-, TMS320-Compatible 4-Wire Serial Interface
- Software-Configurable Unipolar or Bipolar Inputs
