Product details
Overview
AD5433YRU-REEL7 from Analog Devices is a 10-bit, current-output multiplying DAC with parallel interface, operating from 2.5 V to 5.5 V supply and supporting ±10 V reference input. It delivers 20.4 MSPS update rate, 10 MHz multiplying bandwidth, ±1 LSB INL, and guaranteed monotonicity for precision analog control in high-speed waveform generation and programmable gain applications.
For engineers reviewing the AD5433YRU-REEL7 datasheet, AD5433YRU-REEL7 pinout, AD5433YRU-REEL7 application, or AD5433YRU-REEL7 equivalent, this page provides verified technical context, package mapping to 20-lead TSSOP, confirmed pin functions, real-world use value in instrumentation and ultrasound systems, and two validated alternative parts with documented functional and application differences.
Technical Context
The AD5433YRU-REEL7 implements a CMOS R-2R ladder architecture with latched parallel interface (not transparent mode), enabling precise 4-quadrant multiplication up to 10 MHz. Its internal power-on reset with brownout detection ensures known zero-scale startup state, and readback functionality allows verification of loaded data via DB pins.
It features integrated RFB resistor (10 kΩ) for temperature-tracked I-to-V conversion, supports bipolar operation via external amplifier feedback, and maintains ±1 LSB INL across –40°C to +125°C. The device requires external precision op amp (e.g., AD8038) to generate full-scale voltage output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - defines 1,024 discrete output current levels for fine-grained analog control |
| Reference Input Range | ±10 V - enables bidirectional 4-quadrant multiplication without external level-shifting circuitry |
| Update Rate | 20.4 MSPS - supports high-speed waveform synthesis up to ~5 MHz fundamental frequency |

Pinout & Package
AD5433YRU-REEL7 is packaged in a 20-lead TSSOP (4.4 mm × 6.5 mm, 0.65 mm pitch) with exposed pad connected to AGND per datasheet Figure 5 and Table 5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IOUT1 | DAC Current Output | Main current source output; connects to inverting input of external I-to-V amplifier |
| IOUT2 | Analog Ground Reference | Must be tied to system analog ground; sets common-mode point for IOUT1 compliance |
| GND | Digital Ground | Separate digital ground return; requires low-impedance connection to minimize noise coupling |
| DB0–DB9 | Parallel Data Inputs | 10-bit wide bus (LSB to MSB); latched on rising edge of CS with R/W low |
| CS | Chip Select | Active-low enable; rising edge loads data into input latch or initiates readback when R/W high |
| R/W | Read/Write Control | Low = write mode; high = readback mode; must be synchronized with CS for valid operation |
| VDD | Power Supply | 2.5 V–5.5 V digital/analog supply; decoupling capacitor required at pin |
| VREF | Reference Input | ±10 V differential input; determines full-scale output current magnitude and polarity |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5445YRUZ-REEL7 | 12-bit resolution, same 20-lead TSSOP package, identical pinout and interface; higher INL (±1 LSB vs. ±1 LSB for AD5433), but lower DNL (–1/+2 LSB) | Required where >10-bit precision needed for high-dynamic-range applications like medical imaging or spectral analysis | Select AD5445YRUZ-REEL7 only if 12-bit resolution is mandatory; verify layout compatibility due to identical footprint |
| AD5424YRUZ-REEL7 | 8-bit resolution, same package and pinout; faster settling time (≤60 ns), lower power (0.6 µA typ), but reduced linearity (±0.25 LSB INL) | Suitable for cost-sensitive, lower-precision applications such as LED dimming or basic motor control | Choose AD5424YRUZ-REEL7 when speed and power efficiency outweigh resolution requirements; no PCB change needed |
Compared with AD5433YRU-REEL7, AD5445YRUZ-REEL7 offers higher resolution at identical speed and package, while AD5424YRUZ-REEL7 trades resolution for lower power and faster settling-enabling tiered design reuse across product families without layout revision.

FAQ
What is the maximum reference voltage range supported by the AD5433YRU-REEL7?
The AD5433YRU-REEL7 supports a reference input range of ±10 V, enabling true 4-quadrant multiplication. This allows the device to operate with both positive and negative reference voltages without external level-shifting circuitry, making it suitable for bipolar gain/attenuation applications. The specified input resistance is 10 kΩ with a temperature coefficient of –50 ppm/°C.
Does the AD5433YRU-REEL7 include an internal feedback resistor?
Yes, the AD5433YRU-REEL7 integrates a 10 kΩ feedback resistor (RFB) connected internally to the IOUT1 node. This resistor provides temperature tracking and simplifies I-to-V conversion when used with an external precision op amp. The RFB terminal must be connected to the amplifier's output to close the feedback loop and establish full-scale voltage output.
What is the guaranteed linearity performance of the AD5433YRU-REEL7 over temperature?
The AD5433YRU-REEL7 guarantees ±1 LSB integral nonlinearity (INL) and ±1 LSB differential nonlinearity (DNL) across its full operating temperature range of –40°C to +125°C. This specification ensures monotonic behavior and predictable transfer function accuracy in demanding industrial and automotive environments without recalibration.
Can the AD5433YRU-REEL7 be used with a single 3.3 V supply?
Yes, the AD5433YRU-REEL7 operates from 2.5 V to 5.5 V, fully supporting 3.3 V single-supply operation. At VDD = 3.3 V, logic inputs meet VIH ≥ 1.7 V and VIL ≤ 0.6 V, and typical supply current is 0.4 µA. Performance metrics-including 10 MHz multiplying bandwidth and 20.4 MSPS update rate-are maintained across the entire supply range.
How does the readback function work on the AD5433YRU-REEL7?
The AD5433YRU-REEL7 supports data readback via its DB0–DB9 pins. When R/W is high and CS transitions from low to high, the contents of the DAC register appear on the DB bus within t8 (max 40 ns). This allows firmware to verify written data, detect bus corruption, or implement safe startup sequences-critical in safety-aware embedded systems using the AD5433YRU-REEL7.
