Product details
Overview
AD5441BCPZ-REEL7 from Analog Devices is a 12-bit serial-input multiplying DAC in an 8-lead LFCSP package, delivering true 12-bit accuracy (±0.5 LSB INL/DNL), 5 µs settling time, and 1.9 MHz 4-quadrant multiplying bandwidth. It operates from 2.5 V to 5.5 V, draws only 1 µA at 5 V, and supports unipolar 2-quadrant or bipolar 4-quadrant configurations for precision programmable gain control in industrial PLCs.
For engineers reviewing the AD5441BCPZ-REEL7 datasheet, AD5441BCPZ-REEL7 pinout, AD5441BCPZ-REEL7 application, or AD5441BCPZ-REEL7 equivalent, key selection criteria include guaranteed monotonicity across −40°C to +125°C, low 40 nV·s glitch impulse, ±5 nA IOUT leakage at 000H code, and compatibility with standard 3-wire SPI-like serial interface using CLK, SRI, and level-sensitive LD.
Technical Context
The AD5441BCPZ-REEL7 integrates a 12-bit serial-in/parallel-out shift register, double-buffered DAC register, and inverted R-2R ladder with silicon-chrome thin-film resistors (50 ppm/°C tempco) and NMOS current-steering switches. Its reference input exhibits constant 7–15 kΩ input resistance vs. code, enabling stable ac/dc multiplication.
It uses separate clock (CLK) and load (LD) controls for precise timing of data latching into the DAC register, supporting MSB-first serial loading with 5 ns min clock width at 5.5 V. The IOUT current output requires external op amp buffering, with RFB internally matched to optimize gain accuracy in inverting configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12 bits - guarantees 4096 discrete output steps with monotonic behavior across full temperature range. |
| Relative Accuracy (INL) | ±0.5 LSB - ensures end-point linearity error ≤ 0.012% of full-scale, eliminating need for external trimming. |
| Settling Time | 5 µs to ±0.01% FS - enables fast closed-loop response in motion control and calibration systems. |
| Multiplying Bandwidth | 1.9 MHz (−3 dB) - supports high-frequency reference modulation up to ~1.2 MHz for signal synthesis applications. |
| Supply Current | 1 µA at 5 V - allows integration into ultra-low-power industrial sensor nodes without thermal derating. |
| Reference Input Resistance | 7–15 kΩ - provides stable, code-independent loading on voltage or current reference sources. |
| Output Leakage Current | ±5 nA at TA = 25°C - minimizes zero-scale error drift in high-impedance feedback networks. |

Pinout & Package
AD5441BCPZ-REEL7 is housed in an 8-lead LFCSP_WD (CP-8-3) package: 3 mm × 3 mm body, 0.65 mm pitch, exposed pad soldered to ground plane per JEDEC MO-187-AA. Pin 1 indicator located top-left; exposed pad (EP) must be connected to AGND for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VREF (Pin 1) | DAC reference input | Establishes full-scale output; presents constant 7–15 kΩ impedance regardless of digital code-enables direct ac coupling or precision dc referencing. |
| RFB (Pin 2) | Internal feedback resistor terminal | Connects to external op amp output; internally matched to ladder resistors to minimize gain error and tempco in inverting amplifier configurations. |
| IOUT (Pin 3) | Current output node | Sinks full-scale current ≈ VREF/RFB; output impedance varies 7.5–10 kΩ with code-requires low-input-bias-current op amp (e.g., OP42) for accurate voltage conversion. |
| GND (Pin 4) | Analog/digital common ground | Single-point AGND connection required; separates analog return path from noisy digital supplies to preserve 12-bit accuracy. |
| LD (Pin 5) | Level-sensitive load strobe | Active-low signal transfers 12-bit data from shift register to DAC register; timing-critical for synchronized updates in multi-DAC systems. |
| SRI (Pin 6) | Serial data input | MSB-first 12-bit stream; extra leading bits ignored-compatible with standard microcontroller SPI hardware in 3-wire mode (no MISO). |
| CLK (Pin 7) | Positive-edge clock input | Drives serial bit loading; min pulse width 10 ns at 2.5 V-supports >10 MHz update rates with proper PCB layout and termination. |
| VDD (Pin 8) | Positive supply rail | 2.5–5.5 V operation; power dissipation < 5.5 µW-enables direct connection to 3.3 V or 5 V analog supply rails without regulation. |
Key Features
| Feature | Design Value |
|---|---|
| True 12-bit monotonicity | Guaranteed across −40°C to +125°C-eliminates code-dependent nonlinearity in closed-loop calibration systems. |
| Low-glitch impulse | 40 nV·s (typ.)-reduces transient injection during code transitions, critical for low-noise programmable filters and attenuators. |
| Standard and rotated pinout | Shared footprint with DAC8043 family-enables drop-in upgrade path without PCB redesign in legacy industrial modules. |
| Ultra-low quiescent current | 1 µA at 5 V-extends battery life in portable test equipment and reduces self-heating in dense PLC backplanes. |
| 4-quadrant multiplying capability | Supports bipolar reference signals (±10 V) with offset-binary coding-enables direct waveform synthesis and vector modulation. |
| Double-buffered architecture | Independent shift and DAC registers-allows seamless background data loading while maintaining stable analog output. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiplying DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5443BCPZ-REEL7 | 10-bit resolution, same LFCSP package, identical pinout and interface; lower INL (±0.25 LSB) but reduced dynamic range. | Better suited for cost-sensitive 10-bit systems where 12-bit precision is unnecessary-e.g., basic HMI analog outputs. | Select when system resolution requirement is ≤10 bits and BOM cost reduction is prioritized over headroom. |
| DAC8043AIPW | 12-bit, 8-lead TSSOP package; higher max supply current (100 µA); no LFCSP option; pin-compatible but different thermal profile. | Preferred for legacy designs using TSSOP footprints; lacks extended temperature rating (−40°C to +85°C only). | Choose only if existing PCB layout mandates TSSOP and operating temperature stays within commercial range. |
Compared with AD5441BCPZ-REEL7, AD5443BCPZ-REEL7 trades 2 bits of resolution for lower cost and power, while DAC8043AIPW offers pin compatibility at the expense of industrial temperature support and higher quiescent current-making AD5441BCPZ-REEL7 optimal for new high-reliability designs demanding full 12-bit accuracy across harsh environments.

FAQ
What is the maximum reference voltage the AD5441BCPZ-REEL7 can accept?
The AD5441BCPZ-REEL7 supports a reference input voltage range of ±18 V per absolute maximum ratings, but its specified linear operation occurs with VREF up to ±10 V in 4-quadrant mode. For unipolar 2-quadrant use, VREF is typically 2.5–10 V dc. Exceeding ±10 V may degrade INL performance or risk latch-up if not properly current-limited.
Does the AD5441BCPZ-REEL7 require external resistors for basic operation?
No, the AD5441BCPZ-REEL7 includes an internal matched RFB resistor and requires only an external op amp for voltage conversion. Unlike many DACs, it needs no external gain-setting or reference-scaling resistors for standard inverting configurations-reducing component count and board space in compact PLC modules.
Can the AD5441BCPZ-REEL7 operate from a 3.3 V supply?
Yes, the AD5441BCPZ-REEL7 is fully specified for 2.5 V to 5.5 V operation. At 3.3 V, it maintains ±0.5 LSB INL/DNL, 5 µs settling time, and consumes only ~5 µA typical supply current-making it ideal for mixed-voltage industrial systems where 3.3 V logic and 5 V analog rails coexist.
How does the LD pin function in the AD5441BCPZ-REEL7 timing sequence?
The LD pin is a level-sensitive load strobe: when pulled low, it transfers the 12-bit word from the serial shift register into the DAC register on the next rising edge of CLK. This decouples data loading from output update, enabling synchronous multi-DAC operation and glitch-free updates in time-critical motion control loops using AD5441BCPZ-REEL7.
Is the AD5441BCPZ-REEL7 RoHS compliant?
Yes, the AD5441BCPZ-REEL7 is RoHS compliant (indicated by the "Z" suffix per Analog Devices ordering guide). It meets EU Directive 2011/65/EU and contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE).
