Product details
Overview
AD7993BRUZ-1REEL from Analog Devices is a 4-channel, 10-bit successive approximation ADC with I²C-compatible interface, 2 µs conversion time, 188 kSPS throughput at 5 V, and operation from 2.7 V to 5.5 V supply. It integrates a 4-channel multiplexer, track-and-hold amplifier, and out-of-range alert function for industrial sensor monitoring systems.
For engineers reviewing the AD7993BRUZ-1REEL datasheet, AD7993BRUZ-1REEL pinout, AD7993BRUZ-1REEL application, or AD7993BRUZ-1REEL equivalent, key selection criteria include I²C address configurability via AS pin, 16-lead TSSOP package compatibility, −40°C to +125°C temperature range, and support for standard/fast/high-speed I²C modes up to 3.4 MHz.
Technical Context
The AD7993BRUZ-1REEL implements a successive approximation register (SAR) architecture with integrated 4:1 analog multiplexer and track-and-hold, enabling simultaneous sampling control across four single-ended inputs. Its I²C interface supports three operational modes-CONVST-triggered, command-mode, and automatic cycle interval-with programmable limit registers and open-drain ALERT/BUSY output.
It requires an external reference applied to REFIN (1.2 V to VDD), supports full-power bandwidth of 11 MHz at −3 dB, and achieves channel-to-channel isolation of −90 dB. Conversion results are stored in a dedicated register accessible via I²C read operations, with hysteresis and threshold registers configurable per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit SAR ADC: delivers 1024 discrete digital codes for precise analog signal digitization. |
| Conversion Time | 2 µs typical: enables high-speed sampling in real-time control loops and fast-response sensor interfaces. |
| Throughput Rate | 188 kSPS at 5 V with 3.4 MHz SCL: supports high-bandwidth data acquisition without oversampling penalty. |
| Supply Voltage Range | 2.7 V to 5.5 V: ensures compatibility with both 3.3 V and 5 V system rails in mixed-voltage designs. |
| Operating Temperature | −40°C to +125°C: qualified for under-hood automotive, industrial PLC, and harsh-environment applications. |
| I²C Interface Modes | Standard (100 kHz), Fast (400 kHz), High-Speed (3.4 MHz): allows flexible bus speed selection based on system noise and timing constraints. |
| Power Consumption | 1 µA max shutdown current: minimizes quiescent power in battery-operated or energy-sensitive systems. |
Pinout & Package
AD7993BRUZ-1REEL is housed in a 16-lead TSSOP package (4.4 mm × 5.0 mm, 0.65 mm pitch) with exposed pad for thermal performance. Pin functions are validated per Analog Devices Rev. 0 datasheet Figure 3 and Table 5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2,3,4,16 | AGND | Analog ground reference for all internal circuitry; must be connected to low-impedance analog ground plane. |
| 5 | VDD | Main power supply input; decoupling capacitor required between VDD and AGND near the pin. |
| 6 | REFIN | External reference voltage input (1.2 V to VDD); requires 0.1 µF + 1 µF bypass capacitors to AGND. |
| 7,8,9,10 | VIN1–VIN4 | Four single-ended analog inputs; each accepts 0 V to REFIN range with 30 pF input capacitance. |
| 11 | AS | Address select logic input; sets one of five I²C addresses (GND/VDD/float) for multi-device bus configuration. |
| 12 | CONVST | Edge-triggered convert start input; rising edge powers up device, falling edge initiates conversion after ≥1 µs hold time. |
| 13 | ALERT/BUSY | Configurable open-drain output; signals out-of-range condition or active conversion state per register setting. |
| 14 | SDA | I²C bidirectional data line; requires external pull-up resistor to VDD. |
| 15 | SCL | I²C clock input; requires external pull-up resistor to VDD. |
Key Features
| Feature | Design Value |
|---|---|
| Pin-selectable I²C addressing | AS pin enables five unique I²C addresses, allowing up to five AD7993BRUZ-1REEL devices on a single bus without address conflict. |
| Programmable out-of-range alert | Per-channel high/low limit registers and hysteresis control enable autonomous fault detection without host CPU polling. |
| Three conversion trigger modes | Supports hardware-triggered (CONVST), software-commanded, and auto-interval operation-reducing firmware overhead in embedded systems. |
| Low-power shutdown mode | 1 µA max quiescent current extends battery life in portable instrumentation and remote sensing nodes. |
| Wide reference input range | REFIN accepts 1.2 V to VDD, permitting use of internal LDO outputs or precision references for optimized dynamic range. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel, I²C ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7994BRUZ-1REEL | 12-bit resolution, 70.5 dB SINAD min, ±1 LSB INL max vs. AD7993BRUZ-1REEL's 10-bit, 61 dB SINAD, ±0.5 LSB INL. | Higher precision required in medical instrumentation or precision test equipment where 12-bit quantization reduces quantization noise floor. | Select AD7994BRUZ-1REEL when resolution and SNR outweigh cost and power trade-offs; pinout and interface are identical. |
| ADS1114IDGST | 16-bit delta-sigma ADC, 860 SPS max, internal reference, no AS pin, 10-lead VSSOP package. | Lower throughput but higher resolution for slow-varying DC signals like thermocouples or strain gauges in data loggers. | Choose ADS1114IDGST for ultra-high-resolution DC measurements; not suitable for >10 kSPS or multi-device I²C bus configurations. |
Compared with AD7994BRUZ-1REEL, AD7993BRUZ-1REEL offers lower power and cost for 10-bit applications, while ADS1114IDGST trades speed for resolution and eliminates external reference design complexity-but lacks multi-device address flexibility and TSSOP thermal performance.

FAQ
What is the maximum I²C clock frequency supported by AD7993BRUZ-1REEL?
The AD7993BRUZ-1REEL supports I²C high-speed mode up to 3.4 MHz when configured as the -1 variant (confirmed by datasheet Table 3). Standard mode operates at 100 kHz and fast mode at 400 kHz. The AD7993BRUZ-1REEL part number suffix indicates the -1 version, enabling full 3.4 MHz capability with appropriate bus capacitance (≤100 pF).
Does AD7993BRUZ-1REEL require an external reference voltage?
Yes, AD7993BRUZ-1REEL requires an external reference applied to the REFIN pin. The reference voltage must be between 1.2 V and VDD, and the datasheet specifies use of both 0.1 µF and 1 µF bypass capacitors from REFIN to AGND to ensure stability and noise immunity during conversion.
How many analog input channels does AD7993BRUZ-1REEL support, and what is their configuration?
The AD7993BRUZ-1REEL supports four single-ended analog input channels (VIN1–VIN4), each accepting 0 V to REFIN input voltage range. It does not support differential inputs or pseudo-differential modes. Channel selection is handled internally by the integrated 4:1 multiplexer controlled via I²C register writes.
Can AD7993BRUZ-1REEL operate in shutdown mode, and what is its quiescent current?
Yes, AD7993BRUZ-1REEL features a hardware-controlled shutdown mode activated automatically between conversions or via I²C command. Its maximum shutdown current is 1 µA at 3.3 V and 2 µA at 5.5 V (per Table 1), making it suitable for battery-powered applications where ultra-low standby power is critical.
What package type and lead count does AD7993BRUZ-1REEL use?
AD7993BRUZ-1REEL uses a 16-lead TSSOP package (4.4 mm × 5.0 mm body, 0.65 mm lead pitch) with exposed thermal pad. This package is RoHS-compliant, reflow-solderable, and provides superior thermal performance compared to smaller-footprint alternatives like MSOP or VSSOP.
