Product details
Overview
AD4001BRMZ-RL7 from Analog Devices is a 16-bit, 2 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 10-lead MSOP package. It delivers 96.2 dB SNR at 1 kHz, ±0.4 LSB INL, and 8 nJ/sample energy efficiency for high-channel-density data acquisition in space-constrained industrial systems.
For engineers reviewing the AD4001BRMZ-RL7 datasheet, AD4001BRMZ-RL7 pinout, AD4001BRMZ-RL7 application, or AD4001BRMZ-RL7 equivalent, key selection considerations include its 2 MSPS throughput with turbo mode, single 1.8 V supply operation, input overvoltage clamp (±50 mA), SPI/QSPI/MICROWIRE compatibility, and guaranteed 16-bit no-missing-codes performance across temperature.
Technical Context
The AD4001BRMZ-RL7 implements a successive approximation register (SAR) architecture with integrated Easy Drive circuitry that reduces input current to ≤1 μA at 2 MSPS and extends acquisition time to ≥79% of cycle time. Its differential analog front end supports ±VREF input span compression and includes on-chip input overvoltage clamps sinking up to 50 mA per input.
Digital interface operation supports CS-mode (3-/4-wire) and daisy-chain modes via CNV/SDI edge detection, with status bit reporting and configurable SCK timing down to 9.8 ns period (100 MHz). Conversion results are available immediately post-conversion with zero pipeline latency and first-conversion accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit with guaranteed no missing codes - ensures full dynamic range utilization without code gaps in precision measurement. |
| Throughput Rate | 2 MSPS (turbo mode enabled) - enables accurate capture of signals up to 10 MHz bandwidth with oversampling flexibility. |
| INL | ±0.4 LSB max - maintains linearity critical for calibration-sensitive instrumentation and closed-loop control feedback. |
| SNR | 96.2 dB at fIN = 1 kHz, VREF = 5 V - supports >15.7 effective bits for high-fidelity sensor signal digitization. |
| Input Voltage Range | ±VREF (2.4 V–5.1 V) with span compression - allows single-supply system design while preserving full code range. |
| Power Dissipation | 16 mW at 2 MSPS (VDD only) - enables low-thermal-footprint deployment in battery-powered or thermally constrained modules. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, motor drive, and industrial PLC environments. |
Pinout & Package
AD4001BRMZ-RL7 is housed in a 10-lead MSOP (RM-10) package measuring 3 mm × 4.90 mm, 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 (1.71 V–5.5 V logic supply).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REF (Pin 1) | Analog reference input | Accepts external 2.4 V–5.1 V reference; 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 minimize noise coupling into SAR core. |
| IN+ / IN− (Pins 3, 4) | Differential analog inputs | Support ±VREF range; integrated clamp sinks up to 50 mA to protect against transients without external diodes. |
| GND (Pin 5) | Power ground | Primary return path for analog and digital supplies; must connect directly to low-impedance PCB ground plane. |
| CNV (Pin 6) | Convert trigger & interface mode select | Rising edge initiates conversion; logic level at CNV rising edge determines CS vs. daisy-chain mode. |
| SDO (Pin 7) | Serial data output | Outputs 16-bit twos-complement result synchronized to SCK falling edge; tri-stated when CNV high in CS mode. |
| SCK (Pin 8) | Serial clock input | Drives data shift-out; supports 100 MHz max rate (9.8 ns period) in turbo mode for 2 MSPS operation. |
| SDI (Pin 9) | Serial data input / mode select | Low at CNV rising edge selects daisy-chain; high selects CS mode; also accepts configuration register writes. |
| VIO (Pin 10) | Digital I/O supply | Independent 1.71 V–5.5 V rail enabling interface compatibility 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 2 MSPS and extends acquisition phase to 290 ns - eliminates need for dedicated op-amp driver in most applications. |
| Input overvoltage clamp | Sinks ±50 mA per input with 360 ns deactivation - protects ADC and reference from transient surges without external components. |
| Span compression | Shifts input range to 0.1×VREF to 0.9×VREF - enables single-supply operation while retaining full 16-bit code utilization. |
| Turbo mode | Enables 2 MSPS throughput with ≥70 MHz SCK - reduces antialias filter complexity and supports real-time oversampling up to OSR = 1024. |
| Status bit reporting | 6-bit status word includes busy, overrange, and CRC error flags - enables robust real-time system monitoring without additional GPIO. |

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 | 18-bit resolution, 1 MSPS max throughput, same pinout and Easy Drive features. | Better DC accuracy (±0.25 LSB INL) but lower speed - suited for static calibration over dynamic signal capture. | Select AD4003BRMZ-RL7 when 18-bit resolution and lower THD (−128 dB) outweigh 2 MSPS requirement. |
| ADS8860IDRCT | Texas Instruments 16-bit SAR ADC, 1 MSPS, 1.8 V supply, SPI interface, but no input clamp or span compression. | Lacks integrated overvoltage protection and single-supply span compression - requires external clamping and dual-rail driver. | Choose ADS8860IDRCT only if board layout already accommodates external protection and driver circuitry. |
Compared with AD4001BRMZ-RL7, AD4003BRMZ-RL7 trades speed for higher resolution and lower distortion, while ADS8860IDRCT offers alternate vendor sourcing but demands added external components to match AD4001BRMZ-RL7's integrated signal conditioning capabilities.

FAQ
What is the maximum sampling rate supported by the AD4001BRMZ-RL7?
The AD4001BRMZ-RL7 achieves a maximum throughput of 2 MSPS when turbo mode is enabled and the SCK clock frequency is ≥70 MHz. This rate is confirmed in the datasheet's Table 4 and requires VIO ≥ 2.7 V for 9.8 ns minimum SCK period. At 1 MSPS, it operates reliably across full temperature range without turbo mode dependency.
Does the AD4001BRMZ-RL7 require an external driver amplifier?
No, the AD4001BRMZ-RL7 does not require an external driver amplifier in most configurations due to its Easy Drive architecture, which reduces input current to ≤1 μA at 2 MSPS and extends acquisition time to 290 ns. The integrated input clamp and span compression further simplify signal conditioning, enabling direct connection to resistive sensors or transformer-coupled sources.
Can the AD4001BRMZ-RL7 operate from a single 1.8 V supply?
Yes, the AD4001BRMZ-RL7 operates from a single 1.8 V analog supply (VDD = 1.71 V to 1.89 V) with independent 1.71 V–5.5 V digital I/O supply (VIO). This dual-rail flexibility allows interfacing with 1.8 V, 2.5 V, 3 V, or 5 V microcontrollers while maintaining full 16-bit performance and −40°C to +125°C operation.
What protection features does the AD4001BRMZ-RL7 include for overvoltage events?
The AD4001BRMZ-RL7 integrates input overvoltage clamps on IN+ and IN− pins capable of sinking up to ±50 mA each, with activation thresholds at 5.25 V (VREF = 5 V) and deactivation within 360 ns. This eliminates the need for external Schottky diodes and prevents reference pin disturbance during transient events, as verified in the Absolute Maximum Ratings and Applications Information sections.
Is the AD4001BRMZ-RL7 pin-compatible with other members of the AD400x family?
Yes, the AD4001BRMZ-RL7 is pin-compatible with AD4003/AD4007/AD4011 in the same 10-lead MSOP and LFCSP packages. Shared pin functions (REF, VDD, IN+, IN−, GND, CNV, SDO, SCK, SDI, VIO) and identical timing allow drop-in replacement where resolution or speed requirements align - e.g., AD4003BRMZ-RL7 for higher resolution at 1 MSPS.
