Product details

Overview

AD4630-24BBCZ from Analog Devices is a dual-channel, simultaneous-sampling, 24-bit SAR ADC with 2 MSPS per channel throughput, ±0.9 ppm INL over −40°C to +125°C, 105.7 dB SNR, and integrated reference buffer. It serves as the precision digitization front-end in high-fidelity data acquisition systems requiring ultra-low distortion and guaranteed no missing codes at full resolution.

For engineers reviewing the AD4630-24BBCZ datasheet, AD4630-24BBCZ pinout, AD4630-24BBCZ application, or AD4630-24BBCZ equivalent, key selection criteria include guaranteed 24-bit linearity across industrial temperature range, Easy Drive™ low-input-current analog interface (0.6 µA at 2 MSPS), Flexi-SPI configurable output lanes (1/2/4 SDO), echo clock mode for digital isolator integration, and internal supply/reference bypass capacitors in 7 mm × 7 mm CSP_BGA.

Technical Context

The AD4630-24BBCZ implements a successive approximation register architecture with simultaneous sampling on two independent channels, enabling true time-aligned capture of differential or single-ended signals. Its Easy Drive™ input stage reduces charge kickback and relaxes external driver requirements via low 0.6 µA acquisition-phase input current and wide common-mode range (−1/128 × VREF to +129/128 × VREF).

Digital interface flexibility includes Flexi-SPI supporting SDR/DDR, 1–4 SDO lanes per channel, and three clocking modes: SPI, echo clock, and host clock (with internal oscillator division). The integrated 2 μF REF bypass capacitor and on-die 1 μF VDD_5V and 0.2 μF VIO capacitors eliminate external bulk capacitance, reducing system footprint and layout sensitivity.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-precision SAR ADC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD4030-24BCPZ	Single-channel, 24-bit, 2 MSPS SAR ADC with 104 dB SNR and ±1.2 ppm INL; lacks integrated REF/VDD bypass caps and Flexi-SPI lane flexibility.	Suitable for space-constrained single-channel systems but requires external decoupling and offers no echo clock mode for isolator designs.	Select AD4630-24BBCZ when dual-channel simultaneity, on-die capacitors, or echo clock timing simplification are required.
LTC2378-24IUK#PBF	Single-channel, 24-bit, 1 MSPS SAR ADC with 104.5 dB SNR and ±1.5 ppm INL; uses standard SPI (no Flexi-SPI), no integrated REF cap, and 6 mm × 6 mm QFN package.	Targeted at lower-throughput, cost-sensitive instrumentation where board area is less constrained and digital isolator integration is not needed.	Choose AD4630-24BBCZ for higher throughput (2 MSPS), guaranteed ±0.9 ppm INL over full temperature range, and reduced system-level BOM count.

Compared with AD4030-24BCPZ and LTC2378-24IUK#PBF, the AD4630-24BBCZ uniquely delivers dual-channel simultaneity, on-package bypass capacitors, echo clock mode for isolator-friendly timing, and tighter ±0.9 ppm INL across −40°C to +125°C - making it optimal for compact, high-reliability, multi-sensor industrial and scientific systems.

FAQ

What is the maximum guaranteed INL for AD4630-24BBCZ across its full operating temperature range?

The AD4630-24BBCZ guarantees ±0.9 ppm integral nonlinearity from −40°C to +125°C, verified across production lots and process corners. This specification ensures no missing codes at 24-bit resolution under worst-case thermal conditions - a key differentiator for calibration-critical applications like metrology and ATE. The AD4630-24BBCZ achieves this via proprietary trimming and on-die temperature compensation.

Does AD4630-24BBCZ support true simultaneous sampling on both channels?

Yes, the AD4630-24BBCZ performs true simultaneous sampling using independent sample-and-hold circuits per channel, triggered by a single CNV rising edge. This eliminates inter-channel skew and preserves phase relationships between signals - essential for power quality analysis, motor control, and differential sensor measurements. The AD4630-24BBCZ maintains <100 ps channel-to-channel crosstalk (−135 dB) at 1 kHz.

How does the Easy Drive™ feature of AD4630-24BBCZ reduce system design complexity?

The Easy Drive™ feature reduces analog front-end complexity by limiting input current to 0.6 µA at 2 MSPS and supporting a wide common-mode range (−1/128 × VREF to +129/128 × VREF). This allows direct connection to low-output-impedance sensors or simplified op-amp buffers, eliminating need for high-slew-rate, low-impedance drivers. The AD4630-24BBCZ also tolerates up to 60 pF input capacitance during acquisition without performance degradation.

Can AD4630-24BBCZ operate with a 4.096 V external reference, and what are the supply voltage requirements?

Yes, the AD4630-24BBCZ supports 4.096 V to 5 V external references. When using 4.096 V, VDD_5V must be set to 4.75 V–5.25 V and REFIN driven within 4.046 V–4.146 V. The internal reference buffer remains active, delivering ±25 µV offset error and ±0.3 µV/°C drift. The AD4630-24BBCZ maintains full 24-bit performance and ±0.9 ppm INL across this reference range.

What packaging and internal passive components are integrated into the AD4630-24BBCZ CSP_BGA?

The AD4630-24BBCZ uses a 7 mm × 7 mm, 64-ball CSP_BGA package with three integrated bypass capacitors: 1 µF on VDD_5V (pins A3/B3), 0.2 µF on VIO (pins A8/B8), and 2 µF on REF (pins D2/D3/E2/E3). These eliminate external bulk capacitance, reduce PCB layer count, and improve noise immunity - particularly beneficial in dense, thermally sensitive layouts. No external REF capacitor is required when using the internal buffer.
