AD4032-24BBCZ

Analog To Digital Converters (ADC) Overview

The AD4032-24BBCZ is a single-channel, 24-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates at a throughput rate of 500 kSPS and features an Easy Drive analog input stage with low input current. The device integrates internal bypass capacitors for power supplies and the reference buffer within its 64-ball CSP_BGA package. Key electrical specifications include a typical signal-to-noise ratio of 108.4 dB, a maximum integral nonlinearity error of ±0.9 ppm across the extended temperature range of −40°C to +125°C, and a total harmonic distortion of −127 dB.

Analog To Digital Converters (ADC) Feature Summary

• High precision: Guaranteed ±0.9 ppm INL and no missing codes at 24 bits from −40°C to +125°C.
• Easy Drive architecture: Low 1.2 μA DC input current and wide common-mode range simplify front-end driver selection.
• Integrated passive components: Internal 1 μF supply and 2 μF reference bypass capacitors reduce system footprint.
• Flexible digital interface: Flexi-SPI supports 1, 2, or 4 SDO lanes and echo clock mode for simplified isolation.

Analog To Digital Converters (ADC) Applications

• Automatic test equipment
• Medical instrumentation
• Seismology
• Scientific instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify that the specific ordering suffix matches the required performance grade and packaging configuration. Confirm that the voltage reference requirements align with the specified VDD_5V ranges for either 5 V or 4.096 V references. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS inputs.

Analog To Digital Converters (ADC) Selection Notes

Select the AD4032-24BBCZ when a single channel with a 500 kSPS data rate is sufficient, as opposed to the 2 MSPS AD4030-24 variant. Consider the integrated reference buffer if sharing a reference source with other system circuitry is required. Verify that the host processor logic levels are compatible with the 1.2 V to 1.8 V VIO range.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD4030-24/AD4032-24 family of high-performance SAR ADCs. The AD4032-24 is the single-channel counterpart to the dual-channel AD4630-24. Both variants share the same core architecture, including the Easy Drive input stage and the 7 mm × 7 mm 64-ball CSP_BGA package.

Analog To Digital Converters (ADC) Replacement Considerations

The AD4030-24BBCZ serves as a functional replacement if a higher throughput rate of 2 MSPS is acceptable. For dual-channel applications requiring simultaneous sampling, the AD4630-24BBCZ is the appropriate alternative within the same product family.
