Product details
Overview
AD7533KP-REEL from Analog Devices is a 10-bit, CMOS, 4-quadrant multiplying DAC in a 20-lead PLCC package, featuring ±0.1% FSR relative accuracy, 600 ns output settling time, and full TTL/CMOS digital interface compatibility. It operates from 5 V to 16 V supply and supports unipolar/bipolar reference inputs up to ±25 V, enabling precision programmable gain control in industrial signal conditioning systems.
For engineers reviewing the AD7533KP-REEL datasheet, AD7533KP-REEL pinout, AD7533KP-REEL application, or AD7533KP-REEL equivalent, this page delivers verified specifications, validated PLCC pin mapping, confirmed 4-quadrant multiplication behavior, real-world use cases in digitally controlled attenuators and function generators, and two technically documented alternative parts for design flexibility.
Technical Context
The AD7533KP-REEL implements a monolithic thin-film R-2R ladder with ten CMOS current switches, delivering endpoint linearity without external trimming. Its binary-weighted current switching between IOUT1 and IOUT2 maintains constant ladder-leg current regardless of digital state, ensuring stable 10-bit resolution across temperature.
It supports both unipolar (2-quadrant) and bipolar (4-quadrant) operation via offset binary coding, with nominal LSB magnitudes of VREF/1024 and VREF/512 respectively. The device requires only an external op amp and reference to form a complete voltage-output DAC, with RFB pin enabling feedback configuration for precise gain scaling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10 bits - defines 1,024 discrete output levels for high-resolution analog control. |
| Relative Accuracy | ±0.1% FSR maximum - guarantees tight endpoint nonlinearity for calibration-critical applications. |
| Settling Time | 600 ns to 0.05% FSR - enables fast update rates in closed-loop control and waveform generation. |
| Reference Input Range | ±25 V - supports wide-range bipolar references and high-voltage signal scaling. |
| Digital Interface | TTL/CMOS compatible - eliminates level-shifting circuitry when interfacing with microcontrollers or FPGAs. |
| Supply Voltage Range | 5 V to 16 V - allows direct integration into legacy 5 V, 12 V, or 15 V industrial power domains. |
| Output Leakage Current | ±5 nA maximum at TA = 25°C - minimizes error in high-impedance I-V conversion stages. |
Pinout & Package
AD7533KP-REEL is housed in a 20-lead Plastic Leaded Chip Carrier (PLCC) package per JEDEC MO-047-AA, with gull-wing leads and pin 1 identifier notch. Thermal performance supports continuous operation up to +85°C ambient.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6, 11, 16 | NC | No connect - must remain unconnected; no internal bonding or function. |
| 2 | IOUT1 | Main current output terminal - sinks binarily weighted current during active switching; connects to op amp inverting input for voltage output. |
| 3 | IOUT2 | Analog ground reference terminal - tied to system analog ground; provides return path for ladder current when all bits are low. |
| 4 | GND | Digital and analog ground common point - requires low-impedance connection to minimize noise coupling. |
| 5, 7–10, 12–15, 17 | BIT 1 to BIT 10 | Parallel digital inputs (MSB to LSB) - accept TTL/CMOS logic levels; drive internal CMOS switches directly without Schottky clamping. |
| 18 | VDD | Positive supply input - powers internal logic and switches; accepts 5 V to 16 V with 2 mA max quiescent current. |
| 19 | VREF | Reference voltage input - sets full-scale output range; polarity agnostic (±VREF supported); 5 kΩ–20 kΩ input resistance. |
| 20 | RFB | Feedback resistor connection - ties external RFB to op amp output to configure gain and convert current to voltage. |
Key Features
| Feature | Design Value |
|---|---|
| 4-Quadrant Multiplying DAC | Accepts ±VREF and generates bipolar output voltage (±VREF × D/1024), enabling true sign-magnitude signal synthesis. |
| Latch-Free Operation | No external latching required - digital inputs directly control CMOS switches, simplifying timing-critical interface designs. |
| Endpoint Linearity | Guaranteed ±0.1% FSR nonlinearity (AD7533KP grade) - eliminates need for post-fabrication calibration in precision instrumentation. |
| Low Power Dissipation | 2 mA max IDD at VDD = 15 V - reduces thermal load in dense PCB layouts and battery-backed systems. |
| Full 5 V to 16 V Supply Range | Operates across industrial and legacy rail voltages without regulator overhead or level translation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit multiplying DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7533KR-REEL | Same 10-bit architecture and spec, but in 16-lead SOIC_W (RW-16) package; ±0.1% FSR accuracy; 5 V to 16 V supply. | SOIC footprint offers smaller board area and surface-mount compatibility vs. PLCC's gull-wing leads. | Select AD7533KR-REEL for space-constrained PCBs where reflow soldering is preferred and lead pitch tolerance permits. |
| AD7520LN | Industry-standard 10-bit multiplying DAC; ±0.05% FSR accuracy; requires external latch; higher power (5 mA typical). | Higher precision but needs latch IC and consumes more current; pinout differs (16-pin PDIP only). | Choose AD7520LN only when sub-0.05% linearity is mandatory and additional board area for latch logic is acceptable. |
Compared with AD7533KP-REEL, AD7533KR-REEL offers identical electrical performance in a smaller SOIC package but lacks PLCC's ruggedness for high-vibration environments; AD7520LN delivers superior accuracy but increases BOM count and power budget, making it less suitable for cost- and size-sensitive industrial designs.

FAQ
What is the operating temperature range for AD7533KP-REEL?
The AD7533KP-REEL is rated for −40°C to +85°C operation, matching the plastic-leaded chip carrier (PLCC) package specification in the AD7533 ordering guide. This range is validated across all electrical parameters including ±0.1% FSR relative accuracy, 600 ns settling time, and TTL/CMOS input compatibility. No derating is required within this span, and the part maintains guaranteed performance up to the upper limit.
Does AD7533KP-REEL require an external latch?
No, AD7533KP-REEL does not require an external latch. Its CMOS switch architecture enables latch-free operation - digital inputs directly control the internal R-2R ladder switches without intermediate storage. This eliminates timing constraints associated with separate latch enable signals and simplifies interface logic compared to legacy DACs like the AD7520, which mandate external latching.
Can AD7533KP-REEL operate with a 5 V supply?
Yes, AD7533KP-REEL supports a 5 V to 16 V supply range per its Absolute Maximum Ratings and functional specifications. At 5 V, it maintains full TTL/CMOS compatibility, 10-bit resolution, and ±0.1% FSR accuracy. Power dissipation drops to ~25 μA in standby, making it viable for low-voltage industrial and portable instrumentation designs without performance trade-offs.
What is the function of the RFB pin on AD7533KP-REEL?
The RFB pin on AD7533KP-REEL connects the DAC's internal feedback node to the output of an external operational amplifier. When configured with a resistor between RFB and the op amp output, it establishes the gain factor for converting the DAC's current output (IOUT1) into a precise voltage output - enabling flexible scaling independent of VREF magnitude and polarity.
How does AD7533KP-REEL support 4-quadrant multiplication?
AD7533KP-REEL supports 4-quadrant multiplication by accepting bipolar reference inputs (±VREF) and interpreting digital words in offset binary format. This allows output voltage to swing positive or negative relative to ground based on both reference polarity and digital code - e.g., code 0x000 produces −VREF, code 0x200 yields 0 V, and code 0x3FF delivers +VREF, enabling true sign-magnitude analog synthesis.
