Product details
Overview
AD5453YRM from Analog Devices is a 14-bit current-output multiplying DAC with 12 MHz reference bandwidth, ±10 V reference input capability, and 50 MHz serial interface. It operates from a single 2.5 V to 5.5 V supply, supports 4-quadrant multiplication, and delivers ±4 LSB total unadjusted error across −40°C to +125°C - enabling precision programmable gain control in ultrasound and composite video signal paths.
For engineers reviewing the AD5453YRM datasheet, AD5453YRM pinout, AD5453YRM application, or AD5453YRM equivalent, key selection criteria include its guaranteed monotonicity, 2.7 MSPS update rate, low 0.4 μA typical current consumption, and compatibility with SPI/QSPI/MICROWIRE interfaces for embedded waveform generation and calibration systems.
Technical Context
The AD5453YRM implements a high-speed R-2R ladder architecture with double-buffered 3-wire serial interface logic, supporting configurable clock-edge sampling (rising or falling) via internal control bits. Its multiplying topology allows direct use of bipolar ±10 V references while powered from a single low-voltage supply.
It integrates an on-chip 9 kΩ feedback resistor (RFB) with −50 ppm/°C TC for temperature-tracked voltage output when paired with an external I-to-V amplifier. Power-on reset with brownout detection ensures deterministic zero-scale startup behavior independent of supply ramp rate.

| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial motor control environments requiring extended thermal robustness. |
Pinout & Package
AD5453YRM is packaged in an 8-lead LFCSP (Lead Frame Chip Scale Package) with exposed pad. The package provides low thermal resistance and compact footprint suitable for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IOUT1 | DAC Current Output | Primary current sink output; requires external I-to-V amplifier to generate voltage output; compliance range supports ±10 V swing with proper amplifier configuration. |
| GND | Analog Ground Reference | Common return path for DAC core and reference inputs; exposed pad must be soldered to PCB ground plane for thermal and noise performance. |
| SCLK | Serial Clock Input | Accepts up to 50 MHz clock; default falling-edge sampling, configurable to rising edge via control bits for timing alignment with host controller. |
| SDIN | Serial Data Input | 16-bit frame input (12 data + 4 control bits); MSB-first protocol compatible with SPI, QSPI, and MICROWIRE standards. |
| RFB | Feedback Resistor Terminal | Connects to op-amp output to close I-to-V conversion loop; integrated 9 kΩ resistor tracks temperature for stable full-scale voltage output. |
| VREF | Bipolar Reference Input | Accepts ±10 V analog reference; enables 4-quadrant multiplication without external level shifters or dual supplies. |
| VDD | Positive Supply | Single 2.5 V–5.5 V supply powers digital and analog sections; low 0.4 μA quiescent current extends battery life in portable systems. |
| SYNC | Frame Synchronization | Active-low enable for 16-bit data latch; rising edge initiates DAC register update after complete data frame is received. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed Monotonic | Ensures no code-to-code output reversal across full temperature range - essential for closed-loop stability in servo and PID control. |
| Power-on Reset with Brownout Detect | Forces DAC output to zero scale at power-up and holds it during supply undervoltage - prevents transient glitches in safety-critical systems. |
| 4-Quadrant Multiplication | Supports multiplication of positive/negative reference voltages by positive/negative digital codes - required for vector modulation and phase-sensitive detection. |
| Integrated RFB Resistor | 9 kΩ ±20% resistor with −50 ppm/°C TC eliminates external component count and improves temperature tracking vs. discrete resistor networks. |
| Low Digital Feedthrough | 0.5 nV-s feedthrough minimizes coupling of digital switching noise into analog output - critical for high-SFDR applications like ultrasound beamforming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiplying DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5452YRM | 12-bit resolution, ±1 LSB INL, lower TUE (±1 LSB), same package and pinout | Better linearity for medium-precision calibration; reduced dynamic range limits SFDR in wideband ultrasound | Select when 12-bit resolution suffices and tighter INL is prioritized over extended code granularity. |
| MAX5722ETE+ | 14-bit, 2.5 V–5.5 V supply, but only ±5 V reference input and no integrated RFB | Lacks 4-quadrant support and requires external feedback network; lower multiplying bandwidth (2 MHz) | Choose only if bipolar reference range is not needed and board space permits discrete RFB implementation. |
Compared with AD5452YRM, AD5453YRM trades slightly higher INL for 4× more codes and wider reference range - critical for high-fidelity waveform synthesis. Against MAX5722ETE+, AD5453YRM offers superior reference flexibility, integrated RFB, and 6× higher multiplying bandwidth, justifying its use in demanding medical and automotive signal chains.

FAQ
What is the maximum reference voltage range supported by the AD5453YRM?
The AD5453YRM supports a reference input range of ±10 V, enabling true 4-quadrant multiplication without external level-shifting circuitry. This specification is guaranteed across the full operating temperature range (−40°C to +125°C) and is independent of the 2.5 V to 5.5 V VDD supply voltage. The ±10 V tolerance is validated per Absolute Maximum Ratings (Table 3) and functional operation is confirmed in the General Description section of the Rev. I datasheet.
Does the AD5453YRM include an internal feedback resistor, and what is its value?
Yes, the AD5453YRM integrates an internal feedback resistor (RFB) with a nominal value of 9 kΩ, specified as 7 kΩ to 11 kΩ across temperature. This resistor features a temperature coefficient of −50 ppm/°C and is connected between the RFB pin and the internal DAC ladder node. It is explicitly used to establish full-scale voltage output when combined with an external current-to-voltage amplifier, as detailed in the Functional Block Diagram and Pin Function Descriptions (Page 7).
Is the AD5453YRM pin-compatible with other members of the AD545x family?
The AD5453YRM shares identical pinouts with the AD5452YRM in both MSOP and LFCSP packages, as confirmed in Figures 4 and 5 of the datasheet. However, it is not pin-compatible with the AD5450/AD5451 in TSOT packages (Figure 3), which use a different pin ordering. Pin compatibility applies only within the same package type and is limited to AD5452/AD5453 variants - no claim is made for drop-in replacement across resolution grades without verifying layout and decoupling requirements.
What is the guaranteed monotonicity behavior of the AD5453YRM over temperature?
The AD5453YRM is guaranteed monotonic across its entire operating temperature range of −40°C to +125°C, meaning no code-to-code output reversals occur. This guarantee is explicitly stated in the Static Performance table (Page 3) and reinforced in the Terminology section, where differential nonlinearity is specified as −1/+2 LSB - a bound sufficient to ensure monotonicity per standard DAC definitions. No additional characterization or external circuitry is required to maintain this behavior.
How does the AD5453YRM handle power-up initialization?
Upon power-up, the AD5453YRM performs an internal power-on reset with brownout detection that initializes all internal registers and latches to zero, forcing the DAC output to zero scale. This behavior is hardware-enforced and does not require external reset sequencing. The reset remains active until VDD exceeds the brownout threshold and stabilizes, ensuring glitch-free startup even with slow or noisy supply ramps - a feature documented in the Features and General Description sections.
