Product details
Overview
AD5453YRM-REEL7 from Analog Devices is a 14-bit current-output multiplying DAC with 12 MHz reference bandwidth, ±10 V reference input range, and 50 MHz serial interface. It operates from 2.5 V to 5.5 V, delivers <0.4 μA typical supply current, and is qualified for automotive applications (−40°C to +125°C). It serves as a precision programmable gain/attenuation element in analog signal chains requiring high-speed, low-power digital control.
For engineers reviewing the AD5453YRM-REEL7 datasheet, AD5453YRM-REEL7 pinout, AD5453YRM-REEL7 application, or AD5453YRM-REEL7 equivalent, key selection criteria include guaranteed monotonicity, 14-bit resolution with ±2 LSB INL, 4-quadrant multiplication capability, and compatibility with SPI/QSPI/MICROWIRE interfaces in space-constrained industrial and automotive systems.
Technical Context
The AD5453YRM-REEL7 implements an R-2R ladder architecture with double-buffered 3-wire serial interface and integrated feedback resistor (RFB = 7–11 kΩ). Its 4-quadrant multiplication supports bipolar reference inputs up to ±10 V while operating from a single 2.5–5.5 V supply, enabling direct use in composite video, ultrasound, and programmable filter designs without external level-shifting.
Power-on reset with brownout detection ensures deterministic zero-scale output at startup. The device uses CMOS submicron process technology to achieve 2.7 MSPS update rate, 100 ns settling time (to ±1 mV of FS), and <2 nV·s digital-to-analog glitch impulse - critical for waveform generation and calibration applications demanding low distortion and fast transient response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit - defines 16,384 discrete output current steps for high-precision gain/offset trimming. |
| Reference Input Range | ±10 V - enables full 4-quadrant multiplication without external op-amp biasing or rail-splitting. |
| Reference Multiplying BW | 12 MHz - supports high-frequency analog signal modulation (e.g., ultrasound beamforming, RF IF gain control). |
| INL (Integral Nonlinearity) | ±2 LSB max - ensures accurate endpoint linearity after zero/full-scale calibration in instrumentation applications. |
| Update Rate | 2.7 MSPS - allows real-time closed-loop control in programmable amplifiers and digitally tuned oscillators. |
| Supply Current | 0.4–10 μA - enables battery-powered portable instrumentation and always-on automotive sensor conditioning. |
| Operating Temperature | −40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood automotive electronics. |
Pinout & Package
AD5453YRM-REEL7 is housed in an 8-lead MSOP package (3 mm × 3 mm) with exposed pad connected to GND. Pin assignments are standardized across the AD5450–AD5453 family and validated per Figure 4 and Table 4 of Rev. I datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IOUT1 | DAC current output terminal | Primary unidirectional current sink; connects to external I/V amplifier for voltage output configuration. |
| GND | Analog/digital ground reference | Common return path; 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 data capture, configurable to rising edge via control bits. |
| SDIN | Serial data input | 16-bit frame (12-bit code + 4-bit control); latched on active SCLK edge synchronized by SYNC. |
| RFB | Integrated feedback resistor terminal | Connects to op-amp output to form precision I/V converter; 7–11 kΩ value with −50 ppm/°C TC. |
| VREF | Reference voltage input | Accepts ±10 V bipolar input; sets full-scale output current (IOUT = VREF / RFB) independent of VDD. |
| VDD | Positive power supply | 2.5–5.5 V single supply; powers logic and internal DAC core; PSRR > 40 dB up to 100 kHz. |
| SYNC | Active-low frame synchronization | Initiates data load into shift register; minimum high time 30 ns; enables multi-DAC synchronization. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed monotonic | Ensures no code-dependent output droop or nonmonotonic transitions across full 14-bit range. |
| Power-on reset with brownout detect | Forces zero-scale output and clears internal registers during supply ramp-up or undervoltage events. |
| Double-buffered serial interface | Prevents partial updates; new data loads to input register first, then transfers to DAC register on SYNC pulse. |
| Integrated RFB resistor | Eliminates external component count and matching errors in I/V conversion; tracks temperature with −50 ppm/°C TC. |
| Low digital feedthrough (0.5 nV·s) | Minimizes coupling noise into sensitive analog outputs when digital lines toggle during idle periods. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiplying DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5452YRMZ-REEL7 | 12-bit resolution, ±0.5 LSB INL, same 8-lead MSOP package and pinout. | Limited to lower-precision gain control where 14-bit resolution is unnecessary. | Select when cost sensitivity outweighs need for 16× finer step size; retains identical layout and firmware interface. |
| AD5662ARMZ-REEL7 | Voltage-output architecture (not current-output), 16-bit resolution, internal reference, no RFB pin. | Requires no external op-amp but lacks 4-quadrant multiplication and ±10 V reference flexibility. | Choose for fixed-reference, low-distortion voltage generation where reference multiplication is not required. |
Compared with AD5452YRMZ-REEL7, the AD5453YRM-REEL7 provides higher resolution and improved linearity for precision calibration; compared with AD5662ARMZ-REEL7, it offers superior reference bandwidth and true 4-quadrant operation at the cost of requiring external amplification.

FAQ
What is the maximum reference voltage range supported by the AD5453YRM-REEL7?
The AD5453YRM-REEL7 supports a reference input range of ±10 V, enabling true 4-quadrant multiplication. This allows bipolar reference signals to directly modulate the DAC's current output without external level-shifting circuitry, making it suitable for applications like programmable filters and composite video generation where both positive and negative reference swings are required. The device maintains specified performance across this full range while operating from a single 2.5–5.5 V supply.
Does the AD5453YRM-REEL7 require an external op-amp to generate a voltage output?
Yes, the AD5453YRM-REEL7 is a current-output DAC and requires an external operational amplifier configured as a current-to-voltage (I/V) converter. However, it integrates an internal feedback resistor (RFB = 7–11 kΩ) that connects between the op-amp output and the RFB pin, simplifying design and improving temperature tracking. The IOUT1 pin sources/sinks current proportional to the digital code and VREF, and the op-amp converts this to a precise voltage output referenced to GND.
Is the AD5453YRM-REEL7 pin-compatible with other members of the AD5450–AD5453 family?
Yes, the AD5453YRM-REEL7 shares identical pinout and package footprint with the AD5452YRMZ-REEL7 in the 8-lead MSOP variant. Both devices use the same TSOT/MSOP/LFCSP pin configurations shown in Figures 3–5 of the datasheet. This allows hardware reuse across 12-bit and 14-bit variants, though firmware must accommodate the increased resolution and updated INL/DNL specifications of the AD5453YRM-REEL7.
What is the significance of the "Y" grade in AD5453YRM-REEL7?
The "Y" grade in AD5453YRM-REEL7 denotes the extended temperature range qualification: −40°C to +125°C. This grade is AEC-Q100 qualified for automotive applications and guarantees full electrical performance across that range, including ±2 LSB INL, 12 MHz multiplying bandwidth, and <0.4 μA typical supply current. The "Y" suffix distinguishes it from commercial-grade versions and confirms suitability for under-hood and safety-critical systems.
How does the AD5453YRM-REEL7 handle power-up initialization?
The AD5453YRM-REEL7 features built-in power-on reset with brownout detection. At power-up, internal shift registers and latches initialize to 0x0000, forcing the DAC output to zero scale. The reset circuit monitors VDD and holds the DAC in reset until supply voltage stabilizes above the brownout threshold, preventing undefined output states during supply ramp-up. This behavior is automatic and requires no external reset circuitry or software initialization sequence.
