Product details
Overview
AD4004BCPZ-RL7 from Analog Devices is a 16-bit, 1 MSPS precision pseudo-differential successive approximation register (SAR) analog-to-digital converter with Easy Drive architecture. It features ±1.0 LSB INL, 93 dB SNR at 1 kHz, 500 kSPS–2 MSPS scalable throughput, and operates from a single 1.8 V supply with 1.71 V–5.5 V logic interface - enabling high-accuracy data acquisition in battery-powered instrumentation and industrial control systems.
For engineers reviewing the AD4004BCPZ-RL7 datasheet, AD4004BCPZ-RL7 pinout, AD4004BCPZ-RL7 application, or AD4004BCPZ-RL7 equivalent, key selection considerations include its 1 MSPS throughput rating (distinct from AD4000/AD4008), high-Z input mode for reduced driver settling burden, input overvoltage clamp (±50 mA), flexible 2.4 V–5.1 V external reference, and guaranteed 16-bit no-missing-codes performance across −40°C to +125°C.
Technical Context
The AD4004BCPZ-RL7 implements a true SAR architecture with no pipeline latency - delivering first-conversion accuracy and deterministic timing. Its Easy Drive features include an extended acquisition phase (790 ns at 1 MSPS) and high-Z input mode, which reduce input settling requirements and enable use of lower-bandwidth, lower-power op-amp drivers without sacrificing AC performance.
It supports SPI/QSPI/MICROWIRE/DSP-compatible serial interfaces with programmable modes (CS or daisy-chain), 16-bit straight-binary output, and separate VIO supply (1.71 V–5.5 V) for mixed-voltage system interfacing. Input span compression allows full-code-range operation without negative supply, while integrated input clamps protect against overvoltage events up to 5.4 V (VREF = 5 V).
Key Specifications

Pinout & Package
AD4004BCPZ-RL7 is housed in a 10-lead 3 mm × 3 mm LFCSP (CP-10-9) package with exposed pad connected to GND. This thermally enhanced, space-efficient封装 supports high-density PCB layouts and meets industrial temperature requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REF | Analog Reference Input | Accepts 2.4 V–5.1 V external reference; requires local 10 µF X7R decoupling to GND for stable conversion accuracy. |
| VDD | Analog Power Supply | 1.71 V–1.89 V single supply; bypassed with 0.1 µF ceramic capacitor to minimize noise coupling into SAR core. |
| IN+ | Pseudo-Differential Analog Input (+) | Samples voltage relative to IN−; supports 0 V to VREF differential range; benefits from high-Z mode for low-settling drive. |
| IN− | Analog Ground Sense | Provides remote analog ground reference point; must be routed with low impedance to minimize common-mode error. |
| GND | Power Ground | Common return for VDD, REF, and digital supplies; tied to exposed pad for thermal and noise integrity. |
| CNV | Convert Control Input | Edge-triggered start signal; selects CS or daisy-chain mode based on SDI state at rising edge; enables busy indicator when low. |
| SDO | Serial Data Output | 16-bit MSB-first output synchronized to SCK; tri-stated when CNV/SDI high in CS mode. |
| SCK | Serial Clock Input | Accepts up to 100 MHz (VIO ≥ 2.7 V); determines maximum achievable throughput and digital power consumption. |
| SDI | Serial Data Input / Mode Select | Configures interface mode (CS vs. daisy-chain) on CNV rising edge; used for register writes and status reads in CS mode. |
| VIO | Digital I/O Supply | Independent 1.71 V–5.5 V logic supply; enables interoperability with 1.8 V, 2.5 V, 3.3 V, or 5 V host processors. |
Key Features
| Feature | Design Value |
|---|---|
| Easy Drive Architecture | Combines high-Z input mode and extended acquisition phase (790 ns) to relax amplifier bandwidth and RC filter design constraints. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD4004BRMZ-RL7 | Same core specs (16-bit, 1 MSPS, ±1.0 LSB INL), but in 10-lead MSOP (3 mm × 4.90 mm) instead of LFCSP; θJA = 147°C/W vs. 114°C/W for CP-10-9. | Preferred where manual assembly or legacy footprint compatibility is required; less thermally efficient than LFCSP in high-power-density designs. | Select AD4004BRMZ-RL7 only if MSOP mechanical fit or rework accessibility outweighs thermal and size advantages of LFCSP. |
| AD4000BCPZ-RL7 | Higher throughput (2 MSPS), identical package and pinout, but higher power (14–16 mW at 2 MSPS) and tighter timing constraints (min. 70 MHz SCK). | Suitable for applications needing >1 MSPS sampling (e.g., motor control feedback), but requires faster clock and more aggressive layout for noise control. | Choose AD4000BCPZ-RL7 only when system sampling requirement exceeds 1 MSPS; otherwise AD4004BCPZ-RL7 offers optimal power/performance trade-off. |
Compared with AD4004BRMZ-RL7, the AD4004BCPZ-RL7 provides superior thermal performance and smaller footprint in LFCSP, while versus AD4000BCPZ-RL7 it delivers identical precision at lower power and relaxed digital interface timing - making it the optimal choice for 1 MSPS industrial and portable instrumentation.

FAQ
What is the maximum sampling rate supported by the AD4004BCPZ-RL7?
The AD4004BCPZ-RL7 is rated for a maximum throughput of 1 MSPS under specified conditions (turbo mode enabled, VREF = 5 V, T = −40°C to +125°C). This is a fixed specification for the AD4004 variant - distinct from the 2 MSPS AD4000 and 500 kSPS AD4008. Achieving 1 MSPS requires minimum SCK frequency of 50 MHz in turbo mode, and timing compliance must be verified per Table 4 of the Rev. F datasheet. The AD4004BCPZ-RL7 maintains guaranteed 16-bit no-missing-codes performance at this rate.
Does the AD4004BCPZ-RL7 require a negative supply voltage for the input driver?
No, the AD4004BCPZ-RL7 does not require a negative supply for the input driver amplifier. Its input span compression feature shifts the effective input range to accommodate single-supply op-amps while preserving access to the full 16-bit code range. This allows rail-to-rail or near-rail-to-rail drivers powered from a single positive supply (e.g., 3.3 V or 5 V) to interface directly with the AD4004BCPZ-RL7's IN+/IN− inputs without signal clipping or loss of resolution.
How does the high-Z mode affect the performance of the AD4004BCPZ-RL7?
High-Z mode on the AD4004BCPZ-RL7 reduces input charging current to ~1 µA (vs. 0.3 nA in acquisition phase), significantly easing driver amplifier settling requirements - especially for high-impedance sources or multiplexed inputs. It improves distortion performance up to 100 kHz but should be disabled for input frequencies above 100 kHz or when using multiplexing due to increased acquisition time. Enabling high-Z mode increases total power by ~1–2 mW at 1 MSPS but enables use of lower-bandwidth, lower-power op-amps such as the ADA4807.
What package type is used for the AD4004BCPZ-RL7, and is the exposed pad internally connected?
The AD4004BCPZ-RL7 uses a 10-lead 3 mm × 3 mm LFCSP package (Analog Devices part number suffix "CP-10-9"). Its exposed pad (EPAD) is electrically connected to GND and must be soldered to a PCB thermal pad tied to the system ground plane. While not strictly required for basic functionality, connecting the EPAD is mandatory to meet thermal specifications (θJC = 33°C/W) and ensure reliable operation at full throughput across the −40°C to +125°C temperature range.
Can the AD4004BCPZ-RL7 operate with a 2.5 V reference voltage?
Yes, the AD4004BCPZ-RL7 supports external reference voltages from 2.4 V to 5.1 V, including 2.5 V. At VREF = 2.5 V, typical SNR drops to 85.5–87.5 dB and THD degrades to −113 dB (fIN = 1 kHz), reflecting the reduced signal swing. However, INL remains ±1.0 LSB, and the device retains full 16-bit resolution with no missing codes. Using 2.5 V reference lowers power in the reference path (0.325 mA at 1 MSPS) and may improve system noise floor when paired with low-noise 2.5 V references like the ADR4525.
