Product details
Overview
LTC2754ACUKG-16#PBF from Analog Devices (formerly Linear Technology) is a quad 16-bit multiplying current-output DAC with SoftSpan™ programmable output ranges (0V–5V, ±2.5V, ±5V, ±10V, etc.), ±1 LSB INL/DNL over temperature, 2 μs settling time, and SPI serial interface with readback. It serves as a precision voltage synthesis engine in high-resolution industrial control loops.
For engineers reviewing the LTC2754ACUKG-16#PBF datasheet, LTC2754ACUKG-16#PBF pinout, LTC2754ACUKG-16#PBF application, or LTC2754ACUKG-16#PBF equivalent, key selection criteria include guaranteed monotonicity across 0°C to 70°C, software-selectable bipolar/unipolar spans, low 0.26 nV·s (3V) / 1.25 nV·s (5V) glitch impulse, and integrated gain/offset trim capability per channel.
Technical Context
The LTC2754ACUKG-16#PBF implements four independent 16-bit DAC cores with per-channel span register control, enabling simultaneous operation in mixed output ranges (e.g., DAC A at ±10V, DAC B at 0V–10V). Its SoftSpan architecture uses internal precision-matched resistor networks (RIN/RCOM/REF = 20kΩ/20kΩ/10kΩ) to configure reference inversion and bipolar offset translation without external components.
It supports both SPI write-and-update and pin-strapped manual span modes via M-SPAN/S2–S0 pins. All on-chip registers-including span, data, and configuration-are verifiable in one instruction cycle, and automatic readback occurs after any register write. Power-on reset and asynchronous CLR pin force all outputs to 0V regardless of active range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - delivers 65,536 discrete output steps with ±1 LSB integral nonlinearity over full temperature range. |
| Output Settling Time | 2 μs - achieves ±0.0015% FS accuracy for 0V→10V step, enabling high-speed closed-loop control updates. |
| Glitch Impulse | 1.25 nV·s @ 5V - minimizes transient injection during code transitions, critical for sensitive analog signal chains. |
| Supply Current | 1 μA max - ultra-low quiescent power supports battery-backed or energy-constrained instrumentation systems. |
| Reference Multiplying BW | 2 MHz - maintains linearity when driven by AC-coupled or modulated reference sources (e.g., in RF calibration). |
| Digital Interface | SPI with SRO readback - enables real-time verification of register contents and fault-tolerant configuration management. |
| Operating Temp | 0°C to 70°C - commercial-grade thermal specification suitable for lab equipment and factory-floor controllers. |
Pinout & Package
52-pin 7 mm × 8 mm QFN package with exposed pad (Pin 53 = GND), requiring PCB soldering for thermal and electrical integrity. Pin functions are fully defined per channel (A/B/C/D) for independent I/V conversion, reference inversion, and trimming.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS/LD (Pin 5) | Synchronous chip select / load input | Active-low SPI enable; double-function as asynchronous LDAC trigger when CS/LD high. |
| IOUT1A–IOUT1D (Pins 48,45,22,19) | Main current outputs | Virtual-ground nodes requiring external op-amp feedback (e.g., LT1469) to generate precise voltage outputs. |
| RINA–RIND (Pins 2,13,28,39) | Reference inverting amplifier inputs | Accept up to ±15V; internally connected to 20kΩ resistors for generating negative reference rails for bipolar operation. |
| VOSADJA–VOSADJD (Pins 47,46,21,20) | Per-DAC offset adjust inputs | 5V input yields –512 LSB offset correction in any range-enables system-level zero calibration without firmware changes. |
| GEADJA–GEADJD (Pins 1,14,27,40) | Per-DAC gain adjust inputs | 5V input yields ±512 LSB gain correction-compensates for reference drift or amplifier gain error across temperature. |
| M-SPAN (Pin 32) | Span configuration mode select | Tie to GND for SPI-controlled SoftSpan; tie to VDD for hardware pin-strapped fixed-range operation (S0–S2). |
Key Features
| Feature | Design Value |
|---|---|
| Software-selectable output ranges | 6 programmable spans (0V–5V, 0V–10V, ±2.5V, ±5V, ±10V, –2.5V–7.5V) per DAC-eliminates need for external range-switching circuitry. |
| Per-channel gain/offset trim | Independent VOSADJ and GEADJ pins per DAC allow field calibration of each output path without shared component tolerance stacking. |
| Register readback verification | All registers (data + span) readable in one SPI transaction-enables deterministic configuration validation in safety-critical applications. |
| Guaranteed monotonicity | 16-bit monotonic behavior over 0°C to 70°C-ensures no code-to-code output reversal in closed-loop servo or PID systems. |
| Low-glitch architecture | 1.25 nV·s glitch impulse at 5V supply-reduces post-transition settling burden on output amplifiers and improves dynamic fidelity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 16-bit DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5764CRUZ | Quad 16-bit voltage-output DAC; no internal reference inversion; requires external op-amps for bipolar ranges. | Higher board area and BOM count due to external gain/offset components; lacks per-channel trim inputs. | Choose when system already uses external precision op-amps and requires simpler digital interface (no readback). |
| LTC2664-16CUH#PBF | Quad 16-bit voltage-output DAC with integrated rail-to-rail output buffers; no SoftSpan range selection. | Fixed 0V–5V/0V–10V ranges only; no ±10V or asymmetric spans; higher supply current (350 μA vs 1 μA). | Choose when output buffering is required and range flexibility is secondary to ease of use and reduced external components. |
Compared with AD5764CRUZ and LTC2664-16CUH#PBF, the LTC2754ACUKG-16#PBF uniquely combines software-configurable bipolar/unipolar spans, per-DAC gain/offset trim, and ultra-low power-making it optimal for space-constrained, multi-range calibration and control systems where flexibility and long-term stability are critical.

FAQ
What output voltage ranges does the LTC2754ACUKG-16#PBF support?
The LTC2754ACUKG-16#PBF supports six software-programmable output ranges per DAC: 0V to 5V, 0V to 10V, –2.5V to 7.5V, ±2.5V, ±5V, and ±10V. These are implemented using internal SoftSpan resistor networks and require external I/V conversion amplifiers. Pin-strapping via M-SPAN/S2–S0 allows fixed-range operation without SPI interaction.
How does the LTC2754ACUKG-16#PBF ensure monotonicity across temperature?
The LTC2754ACUKG-16#PBF guarantees 16-bit monotonicity over its full 0°C to 70°C operating range through laser-trimmed thin-film resistor networks and proprietary DAC core design. This is verified per unit during production test-not just characterized-and documented as ±1 LSB DNL maximum in the Electrical Characteristics table.
Can the LTC2754ACUKG-16#PBF operate from a 3V supply?
Yes, the LTC2754ACUKG-16#PBF operates from a single 2.7V to 5.5V supply. At 3V, it delivers 16-bit performance with ±1 LSB INL/DNL, 0.26 nV·s glitch impulse, and full SPI functionality. Digital input thresholds scale with VDD, and timing parameters (e.g., SCK frequency ≤25 MHz) are specified for this voltage range.
What is the purpose of the RFLAG pin on the LTC2754ACUKG-16#PBF?
The RFLAG pin on the LTC2754ACUKG-16#PBF is an active-low open-drain output that asserts during power-on reset or asynchronous CLR events. It deasserts (goes high) upon execution of an Update command, providing hardware visibility into DAC initialization and clear status-critical for system-level fault detection and synchronization.
Does the LTC2754ACUKG-16#PBF include internal reference buffers or voltage references?
No, the LTC2754ACUKG-16#PBF is a multiplying current-output DAC and does not include internal voltage references or reference buffers. It requires external precision references (e.g., LT6654, REF5025) and external op-amps (e.g., LT1469) for I/V conversion and reference inversion. Its SoftSpan architecture relies on externally supplied reference voltages applied to RIN/REF pins.
