AD4030-24BBCZ

Analog To Digital Converters (ADC) Overview

The AD4030-24BBCZ is a single-channel, 24-bit successive approximation register (SAR) analog-to-digital converter operating at a throughput rate of 2 MSPS. It features Easy Drive technology with an integrated precharge buffer to simplify analog front-end design. The device guarantees ±0.9 ppm maximum integral nonlinearity (INL) and no missing codes across the extended temperature range of −40°C to +125°C. Key electrical parameters include a typical signal-to-noise ratio (SNR) of 108.4 dB, a dynamic range of 109 dB, and power dissipation of 30 mW at full speed. It utilizes a Flexi-SPI interface compatible with 1.2 V to 1.8 V logic levels.

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: Integrated precharge buffer reduces input current to 1.2 μA at DC inputs, easing driver requirements.
• Flexible digital interface: Supports 1, 2, or 4 SDO lanes and optional DDR clocking to reduce serial clock frequency to 10 MHz at 2 MSPS.
• Integrated reference buffer: Low-drift buffer allows use of external references between 4.096 V and 5 V.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BBCZ corresponds to the 64-ball CSP_BGA package variant when sourcing. Confirm that the required throughput matches the AD4030-24 specification of 2 MSPS, as opposed to the 500 kSPS rate of the AD4032-24 variant. Ensure supply voltages align with the specified ranges for VDD_5V and VDD_1.8V based on the selected reference voltage.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high linearity and wide common-mode input ranges without complex front-end buffering. The Easy Drive feature is suitable for systems where reducing the bandwidth requirements of the driving amplifier is critical. Consider the block averaging filter if higher dynamic range up to 155.5 dB is needed at lower effective sample rates.

Analog To Digital Converters (ADC) Part Context

The AD4030-24 is part of the AD4030-24/AD4032-24 family of 24-bit SAR ADCs. It serves as the single-channel counterpart to the dual-channel AD4032-24. Both variants share identical performance characteristics regarding resolution, linearity, and power consumption, differing primarily in channel count and throughput specifications.

Analog To Digital Converters (ADC) Replacement Considerations

The AD4032-24 is the dual-channel equivalent within the same family. For direct pin-compatible replacement in single-channel designs, verify that the additional channels do not impact board layout or power budget constraints.
