Product details
Overview
AD4001BRMZ from Analog Devices is a 16-bit, 2 MSPS precision differential successive approximation register (SAR) analog-to-digital converter optimized for high-accuracy data acquisition in single-supply systems. It features ±0.4 LSB INL, 96.2 dB SNR at 1 kHz, input overvoltage clamp (50 mA), and Easy Drive architecture enabling direct connection to low-power amplifiers without external buffering. It is used in precision instrumentation requiring low-latency, no-missing-codes conversion with minimal signal chain complexity.
For engineers reviewing the AD4001BRMZ datasheet, AD4001BRMZ pinout, AD4001BRMZ application, or AD4001BRMZ equivalent, key selection considerations include its 2 MSPS throughput with turbo mode, 1.8 V VDD operation, ±VREF differential input range (2.4–5.1 V), 10-lead MSOP package, and SPI/QSPI-compatible serial interface supporting daisy-chain and CS modes.
Technical Context
The AD4001BRMZ employs an Easy Drive SAR architecture that reduces input current to ≤1 μA at 2 MSPS and extends acquisition time to ≥79% of the conversion cycle - eliminating need for dedicated ADC drivers. Its high-Z mode, input span compression, and integrated overvoltage clamps enable robust interfacing with single-supply op amps while preserving full 16-bit code range.
It supports flexible digital interfacing via SPI/QSPI/MICROWIRE/DSP-compatible 3- or 4-wire protocols with status bit reporting, daisy-chain capability, and programmable turbo mode. The device operates across −40°C to +125°C with guaranteed 16-bit no-missing-codes performance and linear power scaling versus throughput.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit, guaranteed no missing codes - ensures full dynamic range utilization without code gaps in precision measurement. |
| Throughput Rate | 2 MSPS (turbo mode enabled) - supports accurate capture of signals up to ~10 MHz bandwidth with oversampling flexibility. |
| INL | ±0.4 LSB max - enables <10 ppm absolute linearity error in 0–10 V full-scale systems, critical for calibration-grade DAQ. |
| SNR | 96.2 dB at fIN = 1 kHz, VREF = 5 V - delivers >15.9 effective bits for low-noise sensor and transducer digitization. |
| Input Span Compression | Enables single 1.8 V supply operation while maintaining ±VREF input range - removes need for negative rail in front-end amplifier design. |
| Input Overvoltage Clamp | Sinks up to 50 mA per input - protects against transient overvoltages without external diodes, reducing BOM count and layout area. |
| Power Dissipation | 9.5 mW at 2 MSPS (VDD only) - enables high-channel-density designs in thermally constrained industrial modules. |
Pinout & Package
AD4001BRMZ 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. Pinout is identical to AD4003/AD4007/AD4011 family members.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - 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. |
| 2 - VDD | Core analog supply | 1.71–1.89 V supply; bypassed with 0.1 µF ceramic capacitor to GND to minimize noise coupling into SAR core. |
| 3 - IN+ | Differential analog input (+) | High-impedance input with integrated clamp; paired with IN− for true differential acquisition up to ±VREF. |
| 4 - IN− | Differential analog input (−) | Matches IN+ in voltage range, clamp behavior, and acquisition timing - essential for common-mode rejection >68 dB at 500 kHz. |
| 5 - GND | Power ground | Reference node for all analog and digital supplies; must connect to low-impedance PCB ground plane. |
| 6 - CNV | Convert control input | Rising edge initiates conversion and selects interface mode (CS vs. daisy-chain); also enables SDO in CS mode when low. |
| 7 - SDO | Serial data output | 16-bit twos-complement result synchronized to SCK falling edge; tri-stated when CNV high in CS mode. |
| 8 - SCK | Serial clock input | Drives data shift-out; minimum 70 MHz required for 2 MSPS in turbo mode; supports 1.71–5.5 V logic levels via VIO. |
| 9 - SDI | Serial data input | Configures interface mode on CNV rising edge (high = CS, low = daisy-chain); also carries daisy-chain input data. |
| 10 - VIO | I/O supply | Independent 1.71–5.5 V logic supply - allows seamless interfacing with 1.8 V, 3.3 V, or 5 V microcontrollers/FPGAs. |
Key Features
| Feature | Design Value |
|---|---|
| Easy Drive architecture | Reduces input current to ≤1 μA at 2 MSPS and extends acquisition phase to 290 ns - eliminates need for high-output-current ADC drivers. |
| Input overvoltage clamp | Sinks up to 50 mA per input with 360 ns deactivation - prevents reference disturbance and removes requirement for external protection diodes. |
| Input span compression | Preserves full 16-bit code range using only positive supply - avoids negative rail generation in single-supply signal chains. |
| Oversampled dynamic range | 126 dB at OSR = 1024 - enables software-defined resolution enhancement for low-frequency precision measurements without hardware filter redesign. |
| Wide temperature range | Specified from −40°C to +125°C - supports deployment in harsh industrial and automotive under-hood environments. |

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 | 18-bit resolution, 1 MSPS max throughput, same 10-lead MSOP package and pinout. | Targeted at ultra-high-precision, lower-speed applications where 18-bit resolution outweighs speed requirements. | Select AD4003BRMZ when 16-bit resolution is insufficient and system sampling rate ≤1 MSPS is acceptable. |
| ADS8860IDRCT | Texas Instruments 16-bit SAR ADC; 1 MSPS, 1.8 V supply, but lacks input overvoltage clamp and Easy Drive architecture. | Requires external input protection and driver buffering, increasing signal chain component count and board area. | Choose ADS8860IDRCT only if TI ecosystem integration or specific timing compatibility overrides robustness and simplicity needs. |
Compared with AD4003BRMZ and ADS8860IDRCT, the AD4001BRMZ uniquely balances 2 MSPS speed, 16-bit precision, integrated clamping, and driverless operation - making it optimal for space- and power-constrained high-channel-count DAQ systems demanding first-sample accuracy.

FAQ
What is the maximum sampling rate supported by the AD4001BRMZ?
The AD4001BRMZ achieves a maximum throughput of 2 MSPS when turbo mode is enabled and the SCK clock frequency is ≥70 MHz. At lower SCK rates or in standard mode, the achievable rate drops to 1.86 MSPS or less depending on interface configuration - as detailed in Table 4 of the Rev. C datasheet. This 2 MSPS capability is exclusive to the AD4001 variant; the AD4005 is limited to 1 MSPS.
Does the AD4001BRMZ require an external ADC driver amplifier?
No, the AD4001BRMZ does not require an external ADC driver due to its Easy Drive architecture, which reduces input current to ≤1 μA at 2 MSPS and extends acquisition time to 290 ns. This allows direct connection to low-output-current, rail-to-rail op amps - significantly simplifying signal chain design and reducing power and board area versus traditional SAR ADC implementations.
What reference voltage range is supported by the AD4001BRMZ?
The AD4001BRMZ accepts an external reference voltage (VREF) from 2.4 V to 5.1 V applied to the REF pin. The device maintains specified performance across this range, including ±0.4 LSB INL and 96.2 dB SNR at 5 V. A 10 µF X7R ceramic capacitor must be placed directly between REF and GND to ensure stable reference decoupling and optimal AC performance.
Can the AD4001BRMZ operate from a single 1.8 V supply?
Yes, the AD4001BRMZ operates from a single 1.8 V analog supply (VDD = 1.71 V to 1.89 V) and supports independent I/O logic levels from 1.71 V to 5.5 V via the VIO pin. This dual-supply flexibility enables direct interfacing with 1.8 V FPGAs or microcontrollers while maintaining full 16-bit performance - unlike many competing ADCs requiring ≥2.5 V analog rails.
Is the AD4001BRMZ pin-compatible with other devices in its family?
Yes, the AD4001BRMZ is pin-compatible with the AD4003/AD4007/AD4011 family in both 10-lead MSOP (RM-10) and LFCSP (CP-10-9) packages. This allows drop-in migration between 16-bit and 18-bit variants (e.g., AD4001 ↔ AD4003) or different speed grades without PCB redesign - provided layout accommodates thermal and decoupling requirements of the target variant.
