Product details
Overview
AD5620ARMZ-2REEL7 from Analog Devices is a 12-bit, single-channel, voltage-output nanoDAC with an integrated 2.5 V, 5 ppm/°C on-chip reference, rail-to-rail output amplifier, and 3-wire SPI-compatible serial interface. It delivers ±1 LSB differential nonlinearity, 10 µs settling time, and operates from 4.5 V to 5.5 V supply - ideal for precision digital offset/gain adjustment in industrial process control instrumentation.
For engineers reviewing the AD5620ARMZ-2REEL7 datasheet, AD5620ARMZ-2REEL7 pinout, AD5620ARMZ-2REEL7 application, or AD5620ARMZ-2REEL7 equivalent, key selection criteria include guaranteed 12-bit monotonicity, internal 2.5 V reference accuracy (±0.2% FSR full-scale error), power-down current of 0.48 µA at 5 V, SOT-23-8 package footprint, and SYNC-interrupt–enabled serial write timing compliance up to 30 MHz.
Technical Context
The AD5620ARMZ-2REEL7 implements a resistor-string DAC architecture with a buffered, rail-to-rail output stage and user-accessible feedback node (VFB) for remote sensing. Its internal 2.5 V reference is available at VREFOUT and supports full-scale output of 0 V to 5 V when VDD ≥ 4.5 V.
It features three software-selectable power-down modes (1 kΩ, 100 kΩ, or high-Z output load), power-on reset to 0 V, and Schmitt-triggered digital inputs compatible with SPI, QSPI, MICROWIRE, and DSP interfaces - enabling robust operation in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12 bits - guarantees monotonic transfer function across full code range (0 to 4095) |
| Differential Nonlinearity | ±0.25 LSB max - ensures no missing codes and predictable step response |
| Reference Output | 2.5 V ±5 mV (2.495 V to 2.505 V) with ±5 ppm/°C TC - enables stable 5 V full-scale output without external reference |
| Settling Time | 10 µs max to ±2 LSB for ¼–¾ scale change - supports update rates up to ~100 kSPS in closed-loop systems |
| Power-Down Current | 0.48 µA typ at 5 V - reduces system standby power in battery-powered instruments |
| Supply Range | 4.5 V to 5.5 V - compatible with standard 5 V logic rails and industrial power domains |
| Interface Speed | 30 MHz max SCLK - allows fast configuration and dynamic updates via compact 16-bit serial frame |
Pinout & Package
AD5620ARMZ-2REEL7 is housed in an 8-lead SOT-23 package (JEDEC MO-178AA), optimized for space-constrained PCB layouts and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive power supply input | Accepts 4.5 V–5.5 V; must be decoupled to GND with ≥100 nF ceramic capacitor for noise immunity |
| VREFOUT | Internal reference voltage output | Provides 2.5 V ±5 mV reference; used as gain-setting node or external monitoring point |
| VFB | Inverting input of output amplifier | Connect directly to VOUT for standard operation; left unconnected only in custom remote-sensing configurations |
| VOUT | Analog voltage output | Rail-to-rail (0 V to VDD); capable of sourcing/sinking ±30 mA - supports direct drive of low-impedance loads |
| GND | Analog/digital ground reference | Single ground connection; requires low-impedance return path to minimize PSRR degradation |
| DIN | Serial data input | 16-bit MSB-first frame; latched on falling edge of SCLK; Schmitt-triggered for noise margin |
| SCLK | Serial clock input | Supports up to 30 MHz; timing-critical for setup/hold compliance per Table 4 in Rev. G datasheet |
| SYNC | Frame synchronization (active-low) | Starts 16-bit write cycle; rising edge acts as interrupt to abort incomplete transfers |
Key Features
| Feature | Design Value |
|---|---|
| On-chip 2.5 V reference | 5 ppm/°C drift and ±0.2% FSR full-scale error eliminate need for external precision reference |
| Guaranteed monotonicity | Ensures predictable, glitch-free output transitions across all 4096 codes - critical for closed-loop stability |
| Three power-down modes | Software-selectable output impedance (1 kΩ / 100 kΩ / high-Z) preserves state while minimizing leakage in sleep mode |
| Rail-to-rail output amplifier | Delivers full 0 V–5 V swing into 2 kΩ load with <10 µs settling - suitable for driving ADC references or op-amp inputs |
| SYNC interrupt capability | Enables safe mid-transfer abortion without corrupting DAC register - essential for real-time fault recovery |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5621ARMZ-2REEL7 | Same 12-bit resolution and 2.5 V reference, but uses MSOP-8 package (3 mm × 3 mm vs. SOT-23's 2.9 mm × 1.6 mm) and has identical electrical specs. | Preferred where board layout allows larger footprint and thermal relief is needed; same pinout but different pad geometry. | Select AD5621ARMZ-2REEL7 if MSOP thermal performance or hand-soldering accessibility is prioritized over minimal area. |
| MCP4725A0T-E/CH | 12-bit I²C DAC with internal 2.048 V reference (±20 ppm/°C), 1.8 V–5.5 V supply, and no power-down modes; lacks SYNC interrupt and VFB access. | Better suited for low-pin-count, low-speed embedded systems where I²C bus sharing is required and reference stability is secondary. | Choose MCP4725A0T-E/CH only for cost-sensitive, non-critical applications where ±20 ppm/°C reference drift and absence of SYNC abort are acceptable. |
Compared with AD5621ARMZ-2REEL7, AD5620ARMZ-2REEL7 offers identical performance in a smaller SOT-23 package but with tighter thermal limits; versus MCP4725A0T-E/CH, it provides superior reference stability, deterministic SPI timing, and hardware-level write abort - making it preferable for industrial calibration and real-time control.

FAQ
What is the reference voltage configuration of the AD5620ARMZ-2REEL7?
The AD5620ARMZ-2REEL7 integrates a 2.5 V, 5 ppm/°C on-chip reference, designated as the -2 variant. This reference appears at the VREFOUT pin and sets the full-scale output range to 0 V–5 V when VDD ≥ 4.5 V. The reference is trimmed and characterized across temperature, delivering ±5 mV absolute accuracy at ambient and ±0.2% FSR full-scale error - eliminating need for external reference components in most precision applications.
Does the AD5620ARMZ-2REEL7 support true rail-to-rail output operation?
Yes, the AD5620ARMZ-2REEL7 features a rail-to-rail output amplifier capable of swinging from 0 V to VDD (up to 5.5 V) under load. Tested with RL = 2 kΩ and CL = 200 pF, it achieves full-scale settling within 10 µs to ±2 LSB. The output can source or sink up to ±30 mA, supporting direct interface with op-amps, ADC references, or low-impedance sensors without external buffering.
How does the power-on reset function behave on the AD5620ARMZ-2REEL7?
The AD5620ARMZ-2REEL7 powers up to 0 V and holds that state until a valid 16-bit write occurs - a behavior confirmed for the -2 variant across all grades (A/B/C) and temperature ranges (−40°C to +105°C). This ensures predictable startup in safety-critical systems, preventing undefined output states during power sequencing. The reset is internal and requires no external components.
Can the AD5620ARMZ-2REEL7 operate from a 3.3 V supply?
No - the AD5620ARMZ-2REEL7 is specified only for 4.5 V to 5.5 V operation. While the -1 variant (e.g., AD5620ARMZ-1) supports 2.7 V–3.3 V with a 1.25 V reference, the -2 suffix explicitly denotes the 2.5 V reference version requiring minimum 4.5 V supply to maintain full 0 V–5 V output range and specified performance (e.g., ±1 LSB DNL, 10 µs settling). Operating below 4.5 V violates Absolute Maximum Ratings and invalidates datasheet guarantees.
What is the purpose of the VFB pin on the AD5620ARMZ-2REEL7?
The VFB pin is the inverting input of the internal output amplifier. In standard operation, it is internally connected to VOUT via bond wire - but the pin is brought out to allow external feedback configuration. When used for remote sensing, VFB can be routed back to the load to compensate for IR drop in long traces, maintaining voltage accuracy at the point of use. Leaving VFB unconnected disables remote sensing and defaults to local regulation.
