Description
The AD7691BRMZ is an Analog To Digital Converter (ADC), which is a 4-part component encompassing 18-bit, charge redistribution, successive approximation, and versatile serial interface port. It operates on a single power supply between 2.3 V and 5 V and contains a low-power, high-speed, and 18-bit sampling ADC with no missing codes. It is designed to sample the voltage difference between the IN+ and IN− pins with the reference voltage, REF, which can be applied externally, up to the supply voltage. It is commonly used in battery-powered equipment, data acquisitions, seismic data acquisition systems, DVMs, instrumentation, and medical instruments.

Application Scenarios
The AD7691BRMZ is specifically designed to be used in battery-powered equipment, which requires a minimal amount of power usage. This component can be used in data acquisitions, seismic data acquisition systems, DVMs, instrumentation, and medical instruments.
Comparison
Advantages- Low power usage: The component consumes only 5 mW at 5 V/250 kSPS, and standby current is 1 nA.
- Pin-for-pin compatible: AD7691BRMZ is pin-for-pin compatible with similar 18-bit AD7690 and 16-bit AD7693, AD7688, and AD7687, so no changes are necessary.
- No pipeline delay: This component has no pipeline delay; thus, no additional power is consumed.
- Multiple serial interfaces: It has a versatile serial interface port that supports SPI®, QSPI™, MICROWIRE™, and DSP for the user's convenience.
- High speed: It contains a low-power, high-speed, and 18-bit sampling ADC with no missing codes and can operate up to 250 kSPS.
Disadvantages- The maximum voltage that can be applied to the reference voltage (REF) is limited to the supply voltage, VDD.
