Product details
Overview
AD4005BRMZ-RL7 from Analog Devices is a 16-bit, 1 MSPS precision differential SAR ADC with Easy Drive architecture, ±VREF input range (2.4 V–5.1 V), −40°C to +125°C operation, and integrated input overvoltage clamp. It delivers 96.2 dB SNR at 1 kHz and supports single 1.8 V supply with flexible 1.71 V–5.5 V logic interface - used in high-channel-density precision data acquisition systems.
For engineers reviewing the AD4005BRMZ-RL7 datasheet, AD4005BRMZ-RL7 pinout, AD4005BRMZ-RL7 application, or AD4005BRMZ-RL7 equivalent, key selection criteria include guaranteed 16-bit no-missing-codes performance, 790 ns acquisition time at 1 MSPS, high-Z mode input current ≤1 μA, oversampled dynamic range up to 126 dB (OSR = 1024), and SPI/QSPI/MICROWIRE compatibility with daisy-chain support.
Technical Context
The AD4005BRMZ-RL7 implements a successive approximation register (SAR) architecture with differential sampling, enabling first-conversion accuracy and zero pipeline latency. Its Easy Drive input stage reduces kickback and extends acquisition time to ≥79% of cycle time at 1 MSPS, eliminating need for dedicated ADC drivers.
It features span compression for single-supply operation, input overvoltage clamping (±50 mA sink capability), and a configurable serial interface supporting CS-mode (3-/4-wire) and daisy-chain modes. The reference input accepts 2.4 V–5.1 V externally applied VREF, decoupled via 10 µF X7R ceramic capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit, guaranteed no missing codes - ensures full code coverage without gaps in precision measurement systems. |
| Throughput Rate | 1 MSPS - enables accurate capture of signals up to ~400 kHz (−3 dB BW = 10 MHz) with oversampling flexibility. |
| INL / DNL | ±0.4 LSB / ±0.5 LSB max - maintains linearity critical for calibration-sensitive instrumentation and control loops. |
| SNR / SINAD | 96.2 dB / 96 dB at fIN = 1 kHz, VREF = 5 V - supports >15.6 ENOB in low-noise sensor signal chains. |
| Oversampled DR | 126 dB at OSR = 1024 - allows effective noise reduction in high-dynamic-range applications like vibration monitoring. |
| Power @ 1 MSPS | 8–12.3 mW total (high-Z disabled/enabled) - enables low-power portable and battery-operated precision DAQ designs. |
| Input Voltage Range | ±VREF (2.4 V–5.1 V) differential - simplifies front-end design by accepting full-scale bipolar inputs without level-shifting. |
Pinout & Package
AD4005BRMZ-RL7 is housed in a 10-lead MSOP package (3 mm × 4.90 mm), RoHS-compliant, with exposed pad connected to GND for thermal and noise performance. Pin 1 is REF; pin 5 is GND; pin 6 is CNV (convert trigger and interface mode selector); pin 10 is VIO (independent logic supply).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REF (Pin 1) | Analog reference input | Accepts 2.4 V–5.1 V external VREF; requires local 10 µF X7R decoupling to GND for stable conversion accuracy. |
| VDD (Pin 2) | Analog power supply | 1.71 V–1.89 V single supply; bypassed with 0.1 µF ceramic capacitor to GND for low-noise operation. |
| IN+ / IN− (Pins 3/4) | Differential analog inputs | Support ±VREF full-scale swing; integrated clamp protects against ±50 mA overvoltage events without external diodes. |
| GND (Pin 5) | Power ground | Common return for VDD, REF, and digital supplies; must connect to low-impedance PCB ground plane. |
| CNV (Pin 6) | Convert trigger & interface mode select | Rising edge initiates conversion; logic state at CNV edge selects CS mode (high) or daisy-chain mode (low). |
| SDO (Pin 7) | Serial data output | Outputs 16-bit two's complement result synchronized to SCK; tri-stated when CNV is high in CS mode. |
| SCK (Pin 8) | Serial clock input | Drives data shift-out; minimum 70 MHz required for 1 MSPS in turbo mode (CS mode, VIO > 2.7 V). |
| SDI (Pin 9) | Serial data input | Configures interface mode: high at CNV rising edge enables CS mode; low enables daisy-chain mode. |
| VIO (Pin 10) | Digital I/O supply | Independent 1.71 V–5.5 V logic supply - enables interoperability with 1.8 V, 2.5 V, 3 V, or 5 V host controllers. |
Key Features
| Feature | Design Value |
|---|---|
| Easy Drive input architecture | Reduces input current to ≤1 μA at 1 MSPS and extends acquisition phase to 790 ns - eliminates need for high-speed op-amp driver in most configurations. |
| Input span compression | Enables full 16-bit code range using only positive supply (no negative rail) - simplifies power architecture in single-supply systems. |
| Integrated overvoltage clamp | Sinks up to ±50 mA on IN+/IN− while limiting REF disturbance - removes requirement for external protection diodes and improves system robustness. |
| Turbo mode & status bits | Supports 1 MSPS throughput with reduced SCK rate requirements and optional 6-bit status word - eases timing margin and enables real-time fault detection. |
| Wide temperature range | Specified performance from −40°C to +125°C - suitable for industrial motor control, automotive test equipment, and downhole instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD4003BRMZ-RL7 | Same 10-lead MSOP package and Easy Drive architecture, but rated for 2 MSPS throughput and higher power (16 mW at 2 MSPS). | Targeted at higher-bandwidth applications (e.g., wideband spectrum analyzers) where 1 MSPS is insufficient. | Select AD4003BRMZ-RL7 only if system requires >1 MSPS sustained sampling with identical pinout and feature set. |
| ADS8860IDRCT | 16-bit, 1 MSPS SAR ADC from Texas Instruments; 10-lead WSON package; no integrated overvoltage clamp; requires external reference buffer. | Suitable for cost-sensitive industrial DAQ where input protection and ease-of-drive are handled externally. | Choose ADS8860IDRCT when board space is constrained (2.5 mm × 2.5 mm WSON) and system-level protection is already implemented. |
Compared with AD4005BRMZ-RL7, AD4003BRMZ-RL7 offers higher speed at the cost of increased power and thermal load, while ADS8860IDRCT trades integrated protection and driver simplification for smaller footprint and lower unit cost - making AD4005BRMZ-RL7 optimal for ruggedized, low-component-count precision DAQ designs.

FAQ
What is the maximum achievable throughput for AD4005BRMZ-RL7 in standard CS mode?
The AD4005BRMZ-RL7 achieves 1 MSPS maximum throughput in CS mode when turbo mode is enabled and SCK frequency is ≥70 MHz (VIO > 2.7 V). At lower SCK rates (e.g., 50 MHz), throughput drops to ~1.5 MSPS in 4-wire mode with six status bits enabled. The 1 MSPS rating is guaranteed under all specified conditions including −40°C to +125°C operation and 1.71 V–1.89 V VDD.
Does AD4005BRMZ-RL7 require an external reference voltage source?
Yes, AD4005BRMZ-RL7 requires an external reference voltage applied to the REF pin, with a valid range of 2.4 V to 5.1 V. The device does not include an internal reference; instead, it supports precision external references (e.g., ADR45xx series) decoupled with a 10 µF X7R ceramic capacitor. This architecture ensures optimal SNR and THD performance while allowing system-level reference selection and trimming.
Can AD4005BRMZ-RL7 operate with a 3.3 V logic interface while using 1.8 V analog supply?
Yes, AD4005BRMZ-RL7 supports independent analog and digital supplies: VDD = 1.71 V–1.89 V for analog circuitry and VIO = 1.71 V–5.5 V for digital I/O. With VIO = 3.3 V, the device accepts standard 3.3 V logic levels on SDI/SCK/CNV and drives SDO to 3.3 V-compatible levels - enabling seamless integration with FPGA or microcontroller hosts without level shifters.
How does the input overvoltage clamp in AD4005BRMZ-RL7 protect the ADC during fault conditions?
The AD4005BRMZ-RL7 input clamp sinks up to ±50 mA on IN+ and IN− pins when voltage exceeds VREF + 0.25 V (e.g., 5.25 V at VREF = 5 V), limiting pin voltage to ≤5.4 V. This action prevents damage to internal sampling capacitors and minimizes disturbance on the REF pin - eliminating need for external Schottky diodes. Clamp deactivation occurs within 360 ns after overvoltage removal, restoring normal acquisition.
Is AD4005BRMZ-RL7 pin compatible with other devices in the AD400x family?
Yes, AD4005BRMZ-RL7 is pin compatible with AD4003/AD4007/AD4011 in the same 10-lead MSOP (RM-10) and LFCSP (CP-10-9) packages. Shared pinout includes identical REF, VDD, IN+, IN−, GND, CNV, SDO, SCK, SDI, and VIO assignments - enabling drop-in replacement across speed grades (1 MSPS to 2 MSPS) and resolution variants (16-bit to 18-bit) without PCB redesign.
