Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ARZ-10' against the manufacturer's current ordering guide to confirm pinout compatibility and RoHS status. Ensure the external reference voltage matches the required +2.5 V specification for optimal accuracy. Confirm that the system timing allows for the mandatory 600 ns acquisition period between conversions to maintain datasheet performance levels.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is required with a ±10 V input range. The ARZ variant denotes the surface-mount SOIC package option. Consider the AD7893BR-10 if higher linearity accuracy (±1/2 LSB) is necessary, or the AD7893SQ-10 for extended industrial temperature operation ranging from -55 °C to +125 °C.

Analog To Digital Converters (ADC) Part Context

The AD7893 belongs to Analog Devices' LC2MOS family of fast serial ADCs. This technology combines precision bipolar circuits with low-power CMOS logic. The part is designed to replace discrete solutions by integrating signal scaling, tracking, and conversion into a minimal footprint. It serves as a cost-effective alternative to parallel interface ADCs in space-constrained designs.

Analog To Digital Converters (ADC) Replacement Considerations

The AD7893BR-10 offers improved linearity accuracy while maintaining the same package and electrical characteristics. For extended temperature requirements, the AD7893SQ-10 provides equivalent functionality across a wider thermal range. Verify pin compatibility before substituting these variants.
