Product details
Overview
AD7992BRMZ-1REEL from Analog Devices is a 2-channel, 12-bit successive approximation ADC with I²C-compatible serial interface, operating from 2.7 V to 5.5 V supply and delivering 2 µs typical conversion time. It integrates a 2-channel multiplexer, track-and-hold amplifier, on-chip oscillator, and programmable limit registers. It serves in industrial sensor signal conditioning where dual analog inputs require synchronized low-power digitization with alert-driven monitoring.
For engineers reviewing the AD7992BRMZ-1REEL datasheet, AD7992BRMZ-1REEL pinout, AD7992BRMZ-1REEL application, or AD7992BRMZ-1REEL equivalent, key selection considerations include its 10-lead MSOP package, −40 °C to +125 °C temperature range, I²C address select (AS) pin for multi-device bus configuration, out-of-range ALERT output, and support for standard/fast/high-speed I²C modes depending on variant.
Technical Context
The AD7992BRMZ-1REEL implements a capacitive DAC-based successive approximation architecture with integrated track-and-hold, supporting single-ended analog inputs up to 11 MHz full-power bandwidth. Its I²C interface supports three addressing options via the AS pin and operates in Mode 1 (CONVST-triggered), Mode 2 (command-mode), or Mode 3 (automatic cycle timer).
It features programmable high/low limit registers per channel, hysteresis control, and an open-drain ALERT/BUSY pin configurable as either out-of-range indicator or busy flag. Reference input (VIN2/REFIN) accepts 1.2 V to VDD, enabling flexible dynamic range scaling without external reference ICs.
Key Specifications

| Conversion Time | 2 µs typ - enables sub-microsecond sampling latency critical for fast transient capture |
| Throughput Rate | 188 kSPS max at 5 V - supports high-speed data logging in dual-channel mode with 3.4 MHz I²C clock |
| Analog Input Range | 0 V to REFIN - allows rail-to-rail input scaling relative to externally applied or internally derived reference |
| INL / DNL | ±1 LSB max / +1/−0.9 LSB max - guarantees monotonicity and no missing codes across full temperature range |
| Supply Range | 2.7 V to 5.5 V - interoperates with both 3.3 V and 5 V logic/system domains without level shifters |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive, motor control, and industrial PLC environments |

Pinout & Package
AD7992BRMZ-1REEL is housed in a 10-lead MSOP (Mini Small Outline Package) with 0.5 mm lead pitch, thermally enhanced for industrial reliability and compact PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 CONVST | Edge-triggered convert start input | Rising edge powers up device; falling edge initiates conversion - enables precise timing control independent of I²C bus activity |
| 2, 7 AGND | Analog ground reference | Dedicated low-noise return path for analog circuitry; must be separated from digital ground to preserve SNR |
| 3 VDD | Power supply input | Single 2.7–5.5 V supply powers entire signal chain - eliminates need for separate analog/digital rails |
| 4 VIN2/REFIN | Channel 2 input / reference voltage input | Configurable dual-role pin: in dual-channel mode = second analog input; in single-channel mode = external reference source (1.2–VDD) |
| 5 VIN1 | Channel 1 analog input | Single-ended input with 30 pF input capacitance - requires proper anti-alias filtering for >11 MHz full-power bandwidth |
| 6 AS | I²C address select | Logic level sets one of three I²C addresses (GND/VDD/floating) - enables up to five AD7992 devices on same bus |
| 8 ALERT/BUSY | Open-drain configurable output | Software-selectable as interrupt (out-of-range) or status (busy) - simplifies host microcontroller polling/interrupt handling |
| 9 SDA | I²C bidirectional data line | Open-drain interface requiring external pull-up - compatible with standard/fast/high-speed I²C protocols |
| 10 SCL | I²C clock input | Open-drain clock input - supports up to 3.4 MHz for high-throughput streaming in AD7992-1 variants |
Key Features
| Feature | Design Value |
|---|---|
| 2 µs conversion + 188 kSPS throughput | Enables real-time closed-loop control in motor drives and power converters with minimal latency |
| I²C address select (AS pin) | Allows three distinct I²C addresses per device - supports daisy-chained sensor arrays without address conflicts |
| Programmable channel-specific limit registers | Permits autonomous over/under-range detection without host CPU intervention - reduces firmware overhead |
| Automatic shutdown between conversions | Reduces average current to <1 µA in idle state - extends battery life in portable instrumentation |
| 1.2 V to VDD reference range | Supports direct connection to regulated system supply or precision external reference - avoids dedicated REF IC cost |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit dual-channel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7994BRUZ | 4-channel, 16-TSSOP package, same 12-bit resolution and I²C interface but no high-speed mode support | Requires more PCB area; lacks 3.4 MHz I²C capability - limits throughput in high-data-rate systems | Select when additional analog inputs are needed and space permits larger TSSOP footprint |
| ADS7822U | 2-channel, 12-bit, SPI interface only; 2.7–5.25 V supply; 2 µs conversion but no built-in limit registers or AS pin | No I²C compatibility; requires separate interrupt GPIO for threshold alerts - increases MCU pin count | Choose when existing design uses SPI infrastructure and external supervision logic is already present |
Compared with AD7994BRUZ and ADS7822U, AD7992BRMZ-1REEL uniquely combines I²C address flexibility, autonomous ALERT functionality, and high-speed I²C support in a space-efficient MSOP package - making it optimal for compact, interrupt-driven, multi-node sensor systems.

FAQ
What is the I²C speed capability of AD7992BRMZ-1REEL?
The AD7992BRMZ-1REEL supports standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) I²C modes. Its datasheet confirms full specification compliance up to 3.4 MHz when operating as the AD7992-1 variant - enabling 188 kSPS throughput in command mode at 5 V. This makes AD7992BRMZ-1REEL suitable for high-bandwidth sensor streaming where bus efficiency is critical.
Does AD7992BRMZ-1REEL require an external reference voltage?
Yes, AD7992BRMZ-1REEL requires an external reference voltage applied to the VIN2/REFIN pin when configured in single-channel mode. The reference range is 1.2 V to VDD. In dual-channel mode, it derives reference internally from VDD. This flexibility allows AD7992BRMZ-1REEL to operate with or without a precision external reference, reducing system cost and complexity where absolute accuracy is not required.
How does the AS pin affect AD7992BRMZ-1REEL addressing?
The AS pin on AD7992BRMZ-1REEL selects one of three I²C addresses: grounded → 0100001, tied to VDD → 0100010 (for AD7992-0) or 0100011 (for AD7992-1), or left floating → 0100000. This enables up to five AD7992BRMZ-1REEL devices on a single I²C bus without address collision - essential for distributed sensor networks in industrial control systems.
Can AD7992BRMZ-1REEL operate autonomously without continuous MCU interaction?
Yes, AD7992BRMZ-1REEL supports autonomous operation via its automatic cycle mode (Mode 3), where internal timer triggers conversions at user-defined intervals. Combined with programmable high/low limit registers and ALERT output, it can generate interrupts on out-of-range conditions - allowing the host MCU to remain in low-power sleep until an event occurs. This behavior is fully implemented in AD7992BRMZ-1REEL hardware.
What is the maximum analog input frequency supported by AD7992BRMZ-1REEL?
AD7992BRMZ-1REEL has a full-power bandwidth of 11 MHz at 3 dB and 2 MHz at 0.1 dB, verified under specified test conditions. Its track-and-hold amplifier supports input frequencies up to 11 MHz, making AD7992BRMZ-1REEL suitable for digitizing fast transients in power quality monitoring and ultrasonic sensing applications - provided appropriate anti-alias filtering is used.
