Product details
Overview
AD4007BRMZ from Analog Devices is a high-accuracy, 18-bit, differential successive approximation register (SAR) analog-to-digital converter with Easy Drive architecture, 1 MSPS throughput, ±1.0 LSB INL, 100.5 dB SNR at 1 kHz, and input overvoltage clamp protection up to 50 mA - deployed in precision data acquisition systems for industrial instrumentation.
For engineers reviewing the AD4007BRMZ datasheet, AD4007BRMZ pinout, AD4007BRMZ application, or AD4007BRMZ equivalent, key selection considerations include its 1 MSPS sampling rate, 1.8 V single-supply operation, SPI/QSPI/MICROWIRE-compatible interface, and guaranteed 18-bit no-missing-codes performance across −40°C to +125°C.
Technical Context
The AD4007BRMZ implements an Easy Drive SAR architecture that reduces input kickback and input current to 1 μA at 1 MSPS, enabling direct drive from low-power amplifiers without external buffering. Its long acquisition phase (790 ns at 1 MSPS) and high-Z mode simplify signal chain design while preserving full 18-bit accuracy.
It features differential analog input range of ±VREF (2.4 V to 5.1 V), span compression for single-supply operation, and integrated input overvoltage clamps that sink up to 50 mA - eliminating need for external protection diodes and minimizing reference pin disturbance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 18-bit, guaranteed no missing codes - ensures full dynamic range utilization without code gaps in precision measurement. |
| Throughput Rate | 1 MSPS - supports accurate capture of signals up to ~400 kHz (−3 dB BW = 10 MHz) with oversampling capability. |
| INL | ±1.0 LSB max - enables high-accuracy DC measurements with <±3.8 ppm error across full temperature range. |
| SNR | 100.5 dB at fIN = 1 kHz, VREF = 5 V - delivers >16.7 effective bits for low-noise sensor and instrumentation applications. |
| Power Dissipation | 8–12.3 mW at 1 MSPS (high-Z mode disabled/enabled) - enables low-power, high-density channel designs on 1.8 V supply. |
| Analog Input Range | ±VREF, VREF = 2.4 V to 5.1 V - supports flexible reference selection while maintaining rail-to-rail differential swing. |
| Operating Temperature | −40°C to +125°C - qualified for harsh industrial and automotive under-hood environments. |
Pinout & Package
AD4007BRMZ is housed in a 10-lead, 3 mm × 4.90 mm MSOP package with exposed pad for thermal enhancement and robust grounding. Pin functions are validated per Analog Devices' Rev. D datasheet (Page 10).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+ | Differential analog input positive | Accepts high-impedance, rail-to-rail differential input; protected by internal clamp diode to VREF. |
| IN− | Differential analog input negative | Paired with IN+; common-mode range centered at VREF/2 ±125 mV for optimal CMRR. |
| VDD | Analog power supply | 1.71 V to 1.89 V single supply - powers core SAR and analog front-end; low voltage enables energy-efficient operation. |
| VIO | Digital I/O supply | 1.71 V to 5.5 V logic interface supply - allows interoperability with 1.8 V/2.5 V/3.3 V/5 V digital hosts without level shifters. |
| REF | Reference voltage input | Accepts 2.4 V to 5.1 V external reference; draws only 0.5 mA at 1 MSPS - minimizes reference buffer burden. |
| GND | Analog ground | Primary analog return path; must be separated from digital ground and connected at single point near VDD decoupling. |
| CNV | Conversion start input | Edge-triggered command initiates sampling; timing-critical for synchronization with external clocks or multiplexers. |
| SCK | Serial clock input | Supports up to 100 MHz in turbo mode; low setup/hold requirements (2 ns) ease timing closure in FPGA/microcontroller interfaces. |
| SDO | Serial data output | 18-bit twos-complement output; data valid immediately post-conversion with zero pipeline delay - critical for real-time control loops. |
| SDI | Serial data input | Configures status bit reporting, turbo mode, and high-Z mode via write to internal register - enables runtime reconfiguration. |
Key Features
| Feature | Design Value |
|---|---|
| Easy Drive architecture | Reduces input current to 1 μA at 1 MSPS and extends acquisition phase to 790 ns - eliminates need for dedicated ADC driver amplifier. |
| Input overvoltage clamp | Sinks up to 50 mA during overvoltage events - protects internal circuitry and prevents reference pin disturbance without external diodes. |
| Span compression | Shifts input range to 0.1×VREF to 0.9×VREF - enables full-code-range operation from single 1.8 V supply without negative rail generation. |
| SPI-/QSPI-/MICROWIRE-compatible interface | Operates with 1.8 V to 5 V logic via VIO pin - simplifies integration with diverse host processors and avoids level-shifter components. |
| Oversampled dynamic range | 125 dB at OSR = 256 - enhances resolution for low-frequency vibration or strain monitoring without increasing base sampling rate. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-accuracy SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD4003BRMZ | 2 MSPS throughput, 270 ns conversion time, higher power (16 mW at 2 MSPS) - same pinout and feature set. | Preferred where higher bandwidth (>500 kHz signal content) and faster channel cycling are required. | Select AD4003BRMZ when system demands ≥2 MSPS sampling; AD4007BRMZ remains optimal for 1 MSPS power/performance balance. |
| AD4011BRMZ | 500 kSPS throughput, 1.79 μs acquisition phase, lower power (2.4 mW VDD-only at 500 kSPS) - identical package and interface. | Targeted at ultra-low-power, high-resolution applications where bandwidth ≤200 kHz suffices. | Choose AD4011BRMZ for battery-operated sensors needing <3 mW total power; AD4007BRMZ provides best-in-class 1 MSPS efficiency. |
Compared with AD4003BRMZ and AD4011BRMZ, the AD4007BRMZ uniquely balances 1 MSPS throughput, 12.3 mW max power, and 790 ns acquisition time - making it the optimal choice for industrial DAQ systems requiring both speed and thermal headroom without sacrificing resolution.

FAQ
What is the maximum sampling rate supported by the AD4007BRMZ?
The AD4007BRMZ supports a maximum throughput rate of 1 MSPS, confirmed in Table 1 and Table 4 of the Rev. D datasheet. This rate is achievable in CS mode with turbo mode enabled and SCK ≥ 80 MHz (VIO < 2.7 V) or ≥ 100 MHz (VIO ≥ 2.7 V). At 1 MSPS, the acquisition phase is 790 ns and conversion time is 290 ns, ensuring deterministic timing for real-time control applications using the AD4007BRMZ.
Does the AD4007BRMZ require an external driver amplifier?
No, the AD4007BRMZ does not require an external driver amplifier in most configurations due to its Easy Drive architecture. With input current reduced to 1 μA at 1 MSPS and a 790 ns acquisition phase, it can be driven directly by low-output-impedance sources such as precision op amps or resistive sensor bridges. The AD4007BRMZ datasheet explicitly states this eliminates the need for dedicated ADC drivers in typical industrial signal chains.
What reference voltage range is compatible with the AD4007BRMZ?
The AD4007BRMZ accepts an external reference voltage (VREF) from 2.4 V to 5.1 V, as specified in the REF parameter row of Table 1. At 1 MSPS, it draws only 0.5 mA from the reference source - enabling use with low-power references like the ADR45xx series. The AD4007BRMZ maintains full 18-bit performance across this entire range, supporting flexible system-level voltage scaling without recalibration.
How does the input overvoltage clamp function on the AD4007BRMZ?
The AD4007BRMZ integrates bidirectional input overvoltage clamps on IN+ and IN− pins that activate when voltage exceeds VREF + 0.25 V (e.g., 5.25 V at VREF = 5 V). Each clamp safely sinks up to 50 mA, protecting internal circuitry and minimizing disturbance on the REF pin. This eliminates external protection diodes and is validated per Absolute Maximum Ratings Table 5 - a key reliability feature of the AD4007BRMZ in noisy industrial environments.
Is the AD4007BRMZ pin-compatible with other devices in the AD400x family?
Yes, the AD4007BRMZ is pin-compatible with the AD4000/AD4004/AD4008 family and shares identical 10-lead MSOP pinout with AD4003BRMZ and AD4011BRMZ. This allows drop-in substitution within the same PCB footprint when adjusting throughput (2 MSPS → 1 MSPS → 500 kSPS) without layout changes - a documented mechanical and electrical compatibility confirmed in the "Pin Configurations" section (Page 10) of the AD4007BRMZ datasheet.
