Product details
Overview
AD5629RACPZ-2-RL7 from Analog Devices is a 12-bit, octal, voltage-output DAC with integrated 2.5 V, 5 ppm/°C reference, I²C interface, and rail-to-rail buffered outputs. It delivers monotonic performance, 4 µs power-up time from power-down, and operates from 4.5 V to 5.5 V. Used in precision analog control loops for industrial process instrumentation.
For engineers reviewing the AD5629RACPZ-2-RL7 datasheet, AD5629RACPZ-2-RL7 pinout, AD5629RACPZ-2-RL7 application, or AD5629RACPZ-2-RL7 equivalent, key selection criteria include guaranteed monotonicity, on-chip 2.5 V reference accuracy (±5 mV at 25°C), I²C fast-mode timing compliance (400 kHz), and 16-lead LFCSP package thermal performance (θJA = 30.4°C/W).
Technical Context
The AD5629RACPZ-2-RL7 implements eight independent string DAC cores with rail-to-rail output amplifiers, each driven by a dedicated input register and DAC register. Its internal 2.5 V reference enables a 0 V to 5 V full-scale output range without external components.
It supports three power-down modes per channel, reducing current to 400 nA at 5 V, and features asynchronous LDAC and CLR pins for synchronized updates and zero/midscale resets. The I²C interface includes noise-suppressing input filters and complies with standard (100 kHz) and fast (400 kHz) modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12 bits - defines 4096 discrete output levels with guaranteed monotonicity across full temperature range (−40°C to +105°C) |
| Reference Output | 2.5 V ±5 mV at 25°C, 5 ppm/°C drift - enables stable 0 V to 5 V output scaling without external reference circuitry |
| I²C Speed | Up to 400 kHz fast mode - supports high-throughput configuration of all 8 DACs in <1.5 ms for full register load |
| Power-Down Current | 400 nA at 5 V - allows ultra-low-power hold states in battery-backed or energy-constrained systems |
| Output Settling Time | 2.5 µs to ±2 LSB (¼ to ¾ scale) - ensures rapid analog response for closed-loop control update cycles |
| Supply Range | 4.5 V to 5.5 V - matches standard industrial 5 V rails and supports operation with ±5% tolerance |
| Digital Crosstalk | 0.2 nV·s - minimizes interference between DAC channels during simultaneous updates |
Pinout & Package
AD5629RACPZ-2-RL7 is housed in a 4 mm × 4 mm, 16-lead LFCSP (CP-16-17) package with exposed pad tied to GND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Accepts 4.5 V–5.5 V; requires 10 µF + 0.1 µF decoupling to GND for low-noise DAC operation |
| GND | Ground reference | Common return for analog/digital domains; exposed pad must be soldered to PCB ground plane |
| VOUTA–VOUTH | Analog outputs (DAC A–H) | Rail-to-rail buffered voltage sources; each capable of sourcing/sinking ≥30 mA at VDD = 5 V |
| VREFIN/VREFOUT | Reference I/O | Configurable as 2.5 V output (internal ref enabled) or external reference input (default at power-up) |
| SCL / SDA | I²C clock/data lines | Open-drain, filtered inputs supporting 400 kHz fast mode; require external pull-ups to VDD |
| LDAC | Load DAC strobe | Asynchronous active-low signal to simultaneously update all DAC outputs from input registers |
| CLR | Asynchronous clear | Falling-edge triggered; forces all DACs to zero scale (AD5629R-2 variant) via internal register |
| A0 | I²C address LSB | Sets slave address bit A0; enables up to two AD5629RACPZ-2-RL7 devices on same I²C bus |
Key Features
| Feature | Design Value |
|---|---|
| Octal 12-bit DAC core | Eight independent, monotonic-by-design DACs reduce component count in multi-channel analog control systems |
| Integrated 2.5 V reference | 5 ppm/°C tempco and ±5 mV initial accuracy eliminate need for external precision reference and associated layout area |
| Hardware LDAC function | Enables deterministic, glitch-free simultaneous output updates across all 8 channels-critical for coordinated actuator control |
| Three-tier power-down | Per-channel power-down modes allow selective shutdown while retaining register state and minimizing system wake latency |
| Industrial temperature range | Specified from −40°C to +105°C ensures reliable operation in factory automation, motor drives, and outdoor instrumentation |
Applications
| Process Control Loop | Data Acquisition Calibration |
|---|---|
|
Use Scenario: Generating precise bias voltages for sensor front-end conditioning in PLC analog I/O modules. IC Role / Device Role / Timing Role: Octal DAC provides independent, synchronized setpoints for 8-channel RTD/thermocouple signal chains. Use Value: On-chip 2.5 V reference ensures <±0.01% FSR gain stability over temperature, eliminating calibration drift in field-deployed units. |
Use Scenario: Dynamic offset correction for 16-bit ADC reference buffers in portable test equipment. IC Role / Device Role / Timing Role: DAC H outputs calibrated nulling voltage; other channels drive programmable gain amplifier (PGA) control lines. Use Value: 2.5 µs settling time enables real-time correction within single ADC conversion cycle (≤10 µs), improving effective resolution. |
| Digital Offset Adjustment | Programmable Voltage Source |
|
Use Scenario: Compensating DC offsets in RF transceiver I/Q baseband paths for 5G small-cell radios. IC Role / Device Role / Timing Role: DAC A–D inject fine-grained DC cancellation voltages into differential op-amp summing nodes. Use Value: 0.2 nV·s digital crosstalk prevents coupling-induced image rejection degradation across adjacent I/Q channels. |
Use Scenario: Providing user-configurable supply rails for FPGA I/O banks in reconfigurable embedded systems. IC Role / Device Role / Timing Role: DAC E–H generate four independent, software-tuned 1.2–3.3 V supply references for mixed-voltage domains. Use Value: Rail-to-rail output swing (0 V to 5 V) and 30 mA drive capability support direct connection to low-ESR ceramic loads without external buffers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5669RACPZ-2-RL7 | 16-bit resolution, identical pinout/package, same 2.5 V reference and I²C interface | Required where <1 LSB INL error is mandatory (e.g., metrology-grade calibration standards) | Select when higher resolution outweighs cost and code compatibility constraints; firmware must handle 16-bit register writes. |
| MCP4728-E/UN | 12-bit, I²C, quad DAC (not octal); no internal reference; 2.7–5.5 V supply; SOT-23-8 package | Suitable only for space-constrained, lower-channel-count designs where external reference and board area are acceptable trade-offs | Choose for cost-sensitive, low-pin-count applications with ≤4 channels; not drop-in due to channel count and reference dependency. |
Compared with AD5629RACPZ-2-RL7, AD5669RACPZ-2-RL7 offers 4× finer resolution but higher cost and code depth; MCP4728-E/UN reduces channel count and removes integrated reference, increasing BOM count and layout complexity for octal use cases.

FAQ
What is the full-scale output voltage range of the AD5629RACPZ-2-RL7?
The AD5629RACPZ-2-RL7 uses an internal 2.5 V reference with ×2 gain, delivering a 0 V to 5 V full-scale output range across all eight DAC channels. This range is rail-to-rail and specified over the full industrial temperature range (−40°C to +105°C) with load conditions up to 2 kΩ.
Does the AD5629RACPZ-2-RL7 require an external reference?
No-the AD5629RACPZ-2-RL7 includes a factory-trimmed 2.5 V, 5 ppm/°C internal reference that is disabled at power-up. It is enabled via a software write to the reference control register. External reference operation is supported by connecting to the VREFIN/VREFOUT pin, but it is optional for this variant.
How does the LDAC pin function on the AD5629RACPZ-2-RL7?
The LDAC pin on the AD5629RACPZ-2-RL7 is an asynchronous, active-low hardware strobe. When pulsed low, it simultaneously transfers data from all eight input registers to their corresponding DAC registers, ensuring synchronized analog output updates across all channels with minimal inter-channel skew.
What power-down current does the AD5629RACPZ-2-RL7 draw at 5 V?
In all-power-down mode (all eight DACs disabled), the AD5629RACPZ-2-RL7 draws 400 nA typical at 5 V supply. This ultra-low quiescent current is maintained while preserving register contents, enabling rapid wake-up (<4 µs) without reinitialization overhead.
Is the AD5629RACPZ-2-RL7 pin-compatible with other variants in the AD5629R/AD5669R family?
Yes-AD5629RACPZ-2-RL7 shares identical 16-lead LFCSP pinout and footprint with AD5629RACPZ-1-RL7, AD5629RACPZ-3-RL7, and AD5669RACPZ-2-RL7. Differences are limited to internal reference voltage (1.25 V vs. 2.5 V) and reset behavior (zero/midscale), not physical connectivity or interface logic.
