Product details
Overview
AD4134BCPZ from Analog Devices is a 24-bit, quad-channel simultaneous-sampling precision ADC based on continuous-time sigma-delta (CTSD) architecture. It delivers 108 dB dynamic range at 374 kSPS (FIR filter), −120 dB THD, ±2 ppm INL, and inherent antialias rejection of 102.5 dB in AA2 mode-enabling high-fidelity acquisition in 3-phase power quality analyzers and hardware-in-the-loop test systems.
For engineers reviewing the AD4134BCPZ datasheet, AD4134BCPZ pinout, AD4134BCPZ application, or AD4134BCPZ equivalent, this page provides verified technical context, real-world design meaning for key specs, validated multidevice synchronization behavior, confirmed LFCSP-56 package mapping, and two rigorously cross-checked alternative parts with documented functional trade-offs.
Technical Context
The AD4134BCPZ implements four independent CTSD modulators with integrated asynchronous sample rate converter (ASRC), enabling precise ODR control from 0.01 kSPS to 1496 kSPS at 0.01 SPS resolution. Its alias-free operation eliminates external antialias filters by rejecting signals near MCLK ±160 kHz in AA2 mode.
Each channel supports dc–391.5 kHz bandwidth with <3.3 ns channel-to-channel phase matching and 130.7 dBFS crosstalk suppression. Digital filtering includes low-ripple FIR (161.9 kHz BW, 32 µdB passband ripple), low-latency sinc3 (391.5 kHz BW, 50/60 Hz rejection), and balanced sinc6 (278.4 kHz BW, 1.496 MSPS max ODR).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24-bit, simultaneous sampling across all 4 channels-enables coherent multi-sensor capture without time-skew correction. |
| Max Sampling Rate | 1.496 MSPS (sinc6 filter)-supports high-bandwidth vibration analysis up to 278.4 kHz −3 dB BW. |
| Dynamic Range | 137 dB at 10 SPS (sinc3); 108 dB at 374 kSPS (FIR)-directly enables 16-bit+ effective resolution in low-noise test equipment. |
| INL Error | ±2 ppm of FSR-guarantees <0.0002% full-scale linearity error for precision calibration-grade measurements. |
| Antialias Rejection | 102.5 dB in AA2 mode-replaces discrete 8th-order analog antialias filters in industrial DAQ designs. |
| Phase Matching | 1.57–3.3 ns channel-to-channel skew-ensures sub-degree phase coherence for 3-phase power vector calculations. |
| Power Modes | High performance (556 mW @ 374 kSPS) and low power (343 mW @ 187 kSPS)-enables thermal-aware system partitioning. |
Pinout & Package
AD4134BCPZ is housed in an 8 mm × 8 mm, 56-lead LFCSP with exposed thermal pad (CP-56-9 package). Pin functions are defined per Analog Devices DS Rev. 0, Pages 14–17.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN0± to AIN3± | Differential analog inputs | Four fully isolated input pairs; each accepts ±VREF differential range with 6.25 kΩ input resistance. |
| REFIN/REFGND | External reference interface | Accepts 4.096 V or 5 V reference; draws 5.85 mA (4-ch, HP mode) - requires low-noise 10 µF ceramic + 100 nF bypass. |
| XTAL1/XTAL2 or CLKIN | 48 MHz clock source | Supports crystal (±100 ppm) or CMOS clock; internal oscillator start-up time = 4.4 ms. |
| DCLK, DOUT0–DOUT3 | Data interface clock & outputs | Configurable as master/slave; supports daisy-chaining and minimum I/O mode to reduce isolator count. |
| SCLK, SDI, SDO, CS | SPI control interface | 50 MHz max SCLK; CRC error checking on SPI transfers ensures robust configuration in noisy environments. |
| ODR, FORMATx, MODEx | Pin-control configuration | Enables standalone operation without microcontroller-critical for deterministic boot-time behavior in safety-critical DAQ. |
Key Features
| Feature | Design Value |
|---|---|
| Inherent antialias rejection | 102.5 dB attenuation at MCLK ±160 kHz eliminates need for external analog antialias filters and associated board area/cost. |
| Asynchronous sample rate converter (ASRC) | Enables granular ODR tuning (0.01 SPS steps) and multidevice sync via single signal line-removes jitter-sensitive high-frequency clock routing. |
| Channel averaging (2:1 or 4:1) | Delivers up to 6 dB dynamic range improvement (e.g., 126 dB A-weighted) while preserving bandwidth-ideal for low-SNR acoustic sensor arrays. |
| Three digital filter profiles | FIR (low ripple, frequency-domain analysis), sinc3 (low latency + 50/60 Hz rejection), sinc6 (balanced noise/response)-gives one device flexibility across test domains. |
| Integrated diagnostics | Includes SPI monitoring, memory map integrity check, ODR input frequency validation, and analog overrange detection-reduces firmware validation burden. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision multichannel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7768-4 | 8-channel, 24-bit, 128 kSPS max; uses discrete-time Σ-Δ; no inherent antialiasing; requires external AAF. | Better channel density but lower max ODR and no CTSD alias rejection-suited for lower-bandwidth, high-channel-count systems. | Select AD7768-4 when >4 channels are needed and input BW <100 kHz; avoid if alias rejection or >128 kSPS is required. |
| ADS131M04 | 4-channel, 24-bit, 64 kSPS max; delta-sigma with integrated PGA; no ASRC; 85 dB alias rejection. | Lower power (24 mW) and integrated gain-but lacks CTSD architecture, ASRC, and high ODR flexibility. | Select ADS131M04 for battery-powered portable analyzers where 64 kSPS suffices and board space is constrained. |
Compared with AD7768-4 and ADS131M04, AD4134BCPZ uniquely combines simultaneous 1.496 MSPS sampling, 102.5 dB inherent antialias rejection, and ASRC-based multidevice sync-making it the only option for coherent, high-BW, filterless precision DAQ in compact form factors.

FAQ
What is the maximum output data rate supported by AD4134BCPZ in high performance mode?
The AD4134BCPZ supports up to 1496 kSPS in high performance mode using the sinc6 digital filter. This corresponds to a −3 dB bandwidth of 278.4 kHz and is validated in Table 1 of the Rev. 0 datasheet under "Sinc6 Filter" row. The sinc3 filter also supports 1496 kSPS, while the wideband FIR filter is limited to 374 kSPS in this mode. All values assume AVDD5 = DVDD5 = 5 V and proper decoupling.
Does AD4134BCPZ require an external antialiasing filter?
No, AD4134BCPZ does not require an external antialiasing filter due to its continuous-time sigma-delta architecture. In Antialiasing 2 (AA2) mode, it provides 102.5 dB rejection of tones within MCLK ±160 kHz-verified in Table 1 under "Input Signal Alias Rejection (AAREJ)". This inherent rejection replaces traditional 8th-order analog filters in precision DAQ designs.
How many channels does AD4134BCPZ support, and are they truly simultaneous?
AD4134BCPZ supports four fully independent analog input channels (AIN0± through AIN3±) with true simultaneous sampling. Each channel has its own CTSD modulator and digital filter path. Channel-to-channel phase matching is specified at 1.57–3.3 ns (typ/max), confirming sub-nanosecond timing coherence essential for vector-based power analysis and coherent acoustic beamforming.
What reference voltages are compatible with AD4134BCPZ?
AD4134BCPZ accepts either 4.096 V or 5 V external reference voltage on the REFIN pin, as explicitly stated in Table 1 under "REFIN Voltage (VREF)". Both values are supported in both high performance and low power modes. Reference current draw is 5.85 mA (4-channel, HP mode) and drops to 0.5 µA when REFIN is disabled-enabling flexible reference sourcing strategies.
Can AD4134BCPZ synchronize multiple devices using a single signal line?
Yes, AD4134BCPZ supports multidevice synchronization using a single signal line via its asynchronous sample rate converter (ASRC) in slave mode. As described in the General Description (Rev. 0, p.3), simultaneous sampling across multiple AD4134BCPZ devices is achieved by driving the DCLK input synchronously, with DIG_IF_RESET issued simultaneously-ensuring deterministic phase alignment across boards.
