Product details
Overview
AD7992BRMZ-0REEL 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 features dual single-ended analog inputs (VIN1, VIN2/REFIN), on-chip track-and-hold, and out-of-range alert functionality-used in industrial sensor signal conditioning where compact size and low-power I²C integration are critical.
For engineers reviewing the AD7992BRMZ-0REEL datasheet, AD7992BRMZ-0REEL pinout, AD7992BRMZ-0REEL application, or AD7992BRMZ-0REEL equivalent, key selection considerations include its 10-lead MSOP package, −40 °C to +125 °C temperature range, 188 kSPS maximum throughput in high-speed I²C mode, programmable limit registers, and pin-selectable I²C addressing via AS pin.
Technical Context
The AD7992BRMZ-0REEL implements a capacitive DAC-based successive approximation architecture with integrated track-and-hold, supporting both single- and dual-channel modes. Its I²C interface operates in standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes-enabled only when the device variant is AD7992-1, which this part is confirmed to be per ordering code "-0" suffix and REEL packaging indicating production-grade B-version.
Conversion is triggered via CONVST pin edge, command-mode write, or automatic cycle timer; power management is intrinsic-device powers up only for conversion and returns to shutdown (<1 µA) afterward. Reference input (VIN2/REFIN) accepts 1.2 V to VDD, enabling flexible dynamic range scaling across supply voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - delivers 1 LSB = VREF/4096 quantization step for precise sensor digitization |
| Conversion Time | 2 µs typ - enables sub-microsecond sampling latency critical for real-time control loops |
| Throughput Rate | 188 kSPS max at 5 V, 3.4 MHz fSCL - supports high-speed monitoring of two analog channels without multiplexer overhead |
| Analog Input Range | 0 V to REFIN - allows full-scale use of external reference (1.2 V–VDD) for optimized SNR in varying supply conditions |
| Supply Voltage | 2.7 V to 5.5 V - compatible with both 3.3 V and 5 V industrial logic domains without level-shifting |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, motor drive, and industrial PLC environments |
| Shutdown Current | 1 µA max - ensures ultra-low quiescent power during idle periods in battery-backed systems |
Pinout & Package
AD7992BRMZ-0REEL is housed in a 10-lead MSOP (Mini Small Outline Package) with 0.5 mm pitch, thermally enhanced for industrial ambient operation (θJA = 200 °C/W). The package is RoHS-compliant and rated for reflow up to 260 °C (Pb-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CONVST | Edge-triggered convert start input | Rising edge powers up device; falling edge initiates conversion-enables precise timing control independent of I²C bus activity |
| VIN1 | Analog input channel 1 | Single-ended input referenced to AGND; full-scale range determined by REFIN voltage |
| VIN2/REFIN | Configurable dual-function pin | In dual-channel mode: second analog input; in single-channel mode: external reference input (1.2 V–VDD) |
| AS | I²C address select logic input | Connect to GND/VDD/floating to select one of three I²C addresses-allows up to five devices on same bus |
| ALERT/BUSY | Open-drain configurable output | Signals out-of-range condition (programmable high/low limits) or BUSY status during conversion-replaces external interrupt controller |
| SDA / SCL | I²C bidirectional data / clock | Standard/fast/high-speed I²C interface with internal pull-downs; requires external pull-ups for bus compliance |
| VDD / AGND | Power and analog ground | Dual ground pins (Pins 2 & 7) minimize noise coupling between digital and analog sections |
Key Features
| Feature | Design Value |
|---|---|
| Sequencer operation | Hardware-managed channel sequencing eliminates firmware overhead for dual-input polling |
| Out-of-range indicator | Programmable high/low limit registers with hysteresis enable autonomous over-limit detection without host intervention |
| Automatic cycle mode | Software-configurable conversion interval (TCONVERT × 32) provides deterministic sampling without external timer |
| I²C address flexibility | Three address options per device (via AS pin) support up to five AD7992BRMZ-0REEL units on one bus-ideal for multi-sensor nodes |
| Low-power architecture | Auto-shutdown between conversions reduces average current to <1 µA-extends battery life in portable instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-channel, 12-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7994BRUZ-0 | 4-channel version in 16-TSSOP; identical I²C interface, timing, and specs per channel | Supports higher channel count without increasing board area per channel; lacks ALERT pin | Select when expanding to >2 sensors per node and PCB layout permits TSSOP footprint |
| MCP3221-E/SN | Single-channel, 12-bit, I²C ADC in SOT-23-6; no CONVST, no ALERT, no sequencer; max 100 kSPS | Lower integration-requires external logic for dual-sensor polling; no out-of-range interrupt capability | Choose for cost-sensitive, low-channel-count designs where autonomous alerting is unnecessary |
Compared with AD7994BRUZ-0 and MCP3221-E/SN, AD7992BRMZ-0REEL uniquely balances dual-channel capability, autonomous ALERT signaling, and MSOP compactness-making it optimal for space-constrained, safety-aware industrial nodes requiring minimal host intervention.

FAQ
What is the I²C interface capability of the AD7992BRMZ-0REEL?
The AD7992BRMZ-0REEL supports standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) I²C modes-confirmed by its "-0" suffix denoting the AD7992-1 variant. It uses open-drain SDA/SCL with external pull-ups and offers three I²C addresses via the AS pin, enabling up to five devices on one bus. The AD7992BRMZ-0REEL does not require external clocking or configuration for basic read/write operations.
Does the AD7992BRMZ-0REEL require an external reference voltage?
Yes-the AD7992BRMZ-0REEL requires an external reference applied to the VIN2/REFIN pin when operating in single-channel mode. The reference voltage range is 1.2 V to VDD. In dual-channel mode, the device uses VDD as the reference. A 0.1 µF and 1 µF capacitor must be placed between VIN2/REFIN and AGND for stability. The AD7992BRMZ-0REEL does not include an internal reference.
How does the ALERT function work on the AD7992BRMZ-0REEL?
The ALERT pin on the AD7992BRMZ-0REEL is an open-drain output that becomes active when a conversion result exceeds user-programmed high or low limit registers. It can be software-enabled/disabled and configured with hysteresis to prevent chatter near thresholds. When asserted, it serves as a hardware interrupt-eliminating continuous polling. This behavior is intrinsic to the AD7992BRMZ-0REEL and requires no external components beyond a pull-up resistor.
What are the power consumption characteristics of the AD7992BRMZ-0REEL?
The AD7992BRMZ-0REEL draws ≤1 µA in shutdown mode (interface inactive) and up to 1.4 mA during active conversion at 5 V and 3.4 MHz I²C speed. Its auto-shutdown architecture powers the core only during conversion, minimizing average current. At 3.3 V and 400 kHz I²C, typical operating current is 0.6 mA. These values are measured and specified across −40 °C to +125 °C for the AD7992BRMZ-0REEL B-version.
Can the AD7992BRMZ-0REEL operate with a 3.3 V supply?
Yes-the AD7992BRMZ-0REEL is fully specified for VDD = 2.7 V to 5.5 V, including 3.3 V operation. All key parameters-including 12-bit INL (±1 LSB), 2 µs conversion time, 188 kSPS throughput (at 5 V), and I²C compatibility-are guaranteed across this range. Logic thresholds scale with VDD (e.g., VINH = 0.7×VDD), ensuring robust interfacing with 3.3 V microcontrollers without level shifters.
