Product details
Overview
AD4007BRMZ-RL7 from Analog Devices is a high-accuracy, 18-bit, differential successive approximation register (SAR) analog-to-digital converter optimized for precision data acquisition at 1 MSPS throughput. It features Easy Drive architecture with ≤0.5 μA input current at 1 MSPS, ≥79% acquisition phase, ±1.0 LSB INL, and 100.5 dB SNR at 1 kHz - enabling direct connection to low-power amplifiers in battery-powered instrumentation.
For engineers reviewing the AD4007BRMZ-RL7 datasheet, AD4007BRMZ-RL7 pinout, AD4007BRMZ-RL7 application, or AD4007BRMZ-RL7 equivalent, this page delivers verified specifications, real-world timing behavior, validated alternative options, and application-specific design value - all confirmed against Rev. D datasheet and Analog Devices' official product documentation.
Technical Context
The AD4007BRMZ-RL7 implements a true SAR architecture with no pipeline latency - first conversion is accurate and deterministic. Its Easy Drive input stage reduces kickback and extends acquisition time to 790 ns at 1 MSPS, allowing high-Z mode operation without external driver amplifiers.
It supports flexible reference voltage (2.4 V to 5.1 V), single 1.8 V supply (VDD), and independent logic supply (VIO from 1.71 V to 5.5 V). The SPI-compatible serial interface operates in 3-wire or 4-wire modes with daisy-chain capability and status bit reporting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 18-bit, guaranteed no missing codes - ensures full dynamic range utilization in precision measurement systems. |
| Throughput Rate | 1 MSPS - enables accurate capture of signals up to ~400 kHz (−3 dB BW = 10 MHz) with oversampling support. |
| INL | ±1.0 LSB max - maintains linearity across full temperature range (−40°C to +125°C) for calibrated sensor interfaces. |
| SNR | 100.5 dB at fIN = 1 kHz, VREF = 5 V - delivers >16.6 effective bits for high-fidelity signal digitization. |
| Power (1 MSPS) | 9.3 mW total (VDD + VIO + REF) - enables low-power portable instrumentation without thermal derating. |
| Analog Input Range | ±VREF differential (up to ±5.1 V) - supports wide dynamic range sensors with single-supply front-end simplification. |
| Input Current | ≤0.5 μA/MSPS - eliminates need for high-output-current ADC drivers in multiplexed or high-impedance source applications. |
Pinout & Package
AD4007BRMZ-RL7 is housed in a 10-lead, 3 mm × 4.90 mm MSOP package with exposed pad (RoHS-compliant, moisture sensitivity level 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary analog and digital return path; must be connected to low-impedance system ground plane. |
| IN+ | Differential analog input (+) | Accepts high-impedance, rail-to-rail common-mode inputs (0.1×VREF to 0.9×VREF) with overvoltage clamp protection. |
| IN− | Differential analog input (−) | Complements IN+; differential pair supports ±VREF span compression for single-supply amplifier compatibility. |
| SDI | Serial data input | Configures mode registers (e.g., turbo, high-Z, status bits); compatible with 1.8 V–5 V logic levels via VIO. |
| SCK | Serial clock input | Drives SPI interface; minimum 80 MHz required for full 1 MSPS throughput in turbo mode. |
| SDO | Serial data output | Delivers 18-bit two's complement result immediately post-conversion; high-impedance when not active. |
| CNV | Convert start input | Edge-triggered command initiates sampling; rising edge defines aperture time (1 ns jitter typical). |
| VIO | IO supply voltage | Decouples logic interface from core ADC supply (VDD), enabling mixed-voltage host MCU interfacing. |
| REF | Reference voltage input | Accepts 2.4 V–5.1 V external reference; supplies 0.5 mA at 1 MSPS with <100 μA disturbance during overvoltage events. |
| VDD | Analog/digital core supply | 1.71 V–1.89 V single supply; powers SAR core, internal logic, and reference buffer - scales linearly with throughput. |
Key Features
| Feature | Design Value |
|---|---|
| Easy Drive input architecture | Reduces input current to ≤0.5 μA at 1 MSPS and extends acquisition phase to 790 ns - eliminates need for dedicated op-amp drivers in most precision signal chains. |
| Input overvoltage clamp | Sinks up to 50 mA per input while limiting REF pin disturbance to <100 μA - removes requirement for external clamping diodes in industrial I/O modules. |
| Span compression | Shifts input range to 0.1×VREF to 0.9×VREF - enables use of single-supply op-amps without negative rails while preserving full 18-bit code range. |
| Turbo mode SPI interface | Supports 1 MSPS conversion with 80 MHz SCK and 3-wire protocol - reduces digital IO power vs. standard SPI and simplifies isolation barrier design. |
| High-Z mode | Disables internal sampling capacitor switching during idle - lowers average current by ~20% in burst-sampling applications like portable DMMs. |

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-RL7 | 2 MSPS throughput, 270 ns conversion time, identical pinout and feature set - higher speed but 16 mW power at full rate. | Preferred for high-frequency transient capture (e.g., motor fault detection), less suitable for ultra-low-power battery operation. | Select when system requires >1 MSPS sampling with same footprint and software compatibility. |
| AD4011BRMZ-RL7 | 500 kSPS throughput, 1790 ns acquisition phase, lower power (4.7 mW at 500 kSPS) - same architecture and interface. | Better suited for static or slowly varying measurements (e.g., strain gauge bridges), where extended acquisition improves noise rejection. | Choose for cost-optimized, low-throughput precision systems prioritizing power efficiency over speed. |
Compared with AD4007BRMZ-RL7, AD4003BRMZ-RL7 trades 7.7 mW extra power for 100% throughput increase, while AD4011BRMZ-RL7 saves 4.6 mW at the cost of halved sampling rate - all three share identical pinout, register map, and Easy Drive benefits for seamless family migration.

FAQ
What is the maximum achievable throughput for AD4007BRMZ-RL7 in turbo mode?
The AD4007BRMZ-RL7 achieves 1 MSPS throughput in turbo mode with an 80 MHz SCK clock and VIO ≥ 2.7 V. This is its rated maximum speed - exceeding it risks timing violations and data corruption. The 1000 ns cycle time includes 790 ns acquisition and 210 ns conversion, ensuring first-conversion accuracy without pipeline delay.
Does AD4007BRMZ-RL7 require an external driver amplifier?
No - AD4007BRMZ-RL7's Easy Drive architecture reduces input current to ≤0.5 μA at 1 MSPS and extends acquisition time to 790 ns, enabling direct connection to low-output-impedance sources like precision op-amps or resistive sensor bridges without a dedicated driver stage.
Can AD4007BRMZ-RL7 operate with a 2.5 V reference voltage?
Yes - AD4007BRMZ-RL7 supports VREF from 2.4 V to 5.1 V. At 2.5 V, it delivers 93.5 dB SNR and ±0.75 LSB DNL, maintaining 18-bit no-missing-codes performance. Reference current drops to 0.5 mA at 1 MSPS, reducing REF supply burden.
How does the input overvoltage clamp protect AD4007BRMZ-RL7?
The AD4007BRMZ-RL7 input clamp activates at ~2.68 V (for 2.5 V VREF) or ~5.25 V (for 5 V VREF), sinking up to 50 mA per input. During clamping, REF pin disturbance remains <100 μA - eliminating need for external Schottky diodes in industrial I/O designs subject to wiring faults.
Is AD4007BRMZ-RL7 pin-compatible with other members of the AD400x family?
Yes - AD4007BRMZ-RL7 shares identical 10-lead MSOP pinout, register map, and interface protocol with AD4003BRMZ-RL7 and AD4011BRMZ-RL7. This allows hardware reuse across 500 kSPS, 1 MSPS, and 2 MSPS variants without PCB redesign.
