Product details
Overview
AD5314ARM-REEL7 from Analog Devices is a quad 10-bit buffered voltage-output DAC in a 10-lead MSOP package, operating from 2.5 V to 5.5 V with 500 μA typical supply current at 3 V. It delivers rail-to-rail output swing (0 V to VDD), ±2.5 LSB INL (B version), and simultaneous output update via LDAC. Used in programmable voltage sources for industrial process control.
For engineers reviewing the AD5314ARM-REEL7 datasheet, AD5314ARM-REEL7 pinout, AD5314ARM-REEL7 application, or AD5314ARM-REEL7 equivalent, key selection considerations include guaranteed monotonicity, 3-wire SPI/QSPI/MICROWIRE compatibility, power-down mode (80 nA @ 3 V), double-buffered input logic, and −40°C to +105°C automotive-qualified operation.
Technical Context
The AD5314ARM-REEL7 implements four independent resistor-string DAC channels, each with a dedicated rail-to-rail output buffer amplifier (slew rate: 0.7 V/μs, settling time: 7–9 μs). All DACs share a single unbuffered REFIN pin (0.25 V to VDD range, 45 kΩ input impedance).
Its 3-wire serial interface supports clock rates up to 30 MHz and features SYNC-active-low framing, falling-edge data capture on SCLK, and automatic input buffer power-down after write cycles. Power-on reset forces all DAC outputs to 0 V until first valid write.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10 bits - defines 1,024 discrete output levels per channel |
| INL (B Version) | ±2.5 LSB - ensures accurate transfer function linearity across full code range |
| Supply Current | 500 μA @ 3 V - enables battery-powered portable instrumentation |
| Power-Down Current | 80 nA @ 3 V - reduces system standby power by >6,000× vs. active mode |
| Output Range | 0 V to VDD - supports rail-to-rail analog control without external level-shifting |
| Settling Time | 7 μs (¼ to ¾ scale) - meets timing requirements for fast closed-loop feedback |
| Interface Compatibility | SPI/QSPI/MICROWIRE/DSP - simplifies integration with common microcontrollers |
| Temperature Range | −40°C to +105°C - qualified for under-hood automotive and industrial environments |
Pinout & Package
AD5314ARM-REEL7 is housed in a 10-lead MSOP (Mini Small Outline Package) with exposed pad (GND-connected), measuring 3 mm × 3 mm × 1.1 mm. Pin 1 is VDD; pins 2–4 and 6 are buffered analog outputs (VOUTA–VOUTD); pin 5 is shared reference input (REFIN); pin 7 is GND; pins 8–10 are digital interface signals (DIN, SCLK, SYNC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power supply input | Single 2.5 V–5.5 V rail powers all DACs and buffers; decoupling to GND required |
| VOUTA–VOUTD (Pins 2,3,4,6) | Buffered analog outputs | Rail-to-rail voltage outputs (0 V to VDD) with 25 mA short-circuit capability at 5 V |
| REFIN (Pin 5) | Shared reference input | Unbuffered input accepting 0.25 V–VDD; sets full-scale range for all four DACs |
| GND (Pin 7) | Ground reference | Common return for analog/digital circuitry; exposed paddle must connect to 0 V |
| DIN (Pin 8) | Serial data input | 16-bit shift register accepts command/data; powered down after each write cycle |
| SCLK (Pin 9) | Serial clock input | Falling-edge clocked; supports up to 30 MHz; input buffer auto-powered-down post-write |
| SYNC (Pin 10) | Frame synchronization | Active-low signal enabling 16-bit data transfer; rising edge aborts incomplete writes |
Key Features
| Feature | Design Value |
|---|---|
| Quad 10-bit buffered DACs | Four independent, monotonic channels in one 10-lead MSOP - saves board space vs. discrete solutions |
| Double-buffered input logic | Allows asynchronous loading of DAC registers followed by synchronous output update via LDAC |
| Simultaneous output update | LDAC function enables glitch-free coordinated step changes across all four outputs |
| Rail-to-rail output amplifiers | 0 V to VDD swing with 0.7 V/μs slew rate - eliminates need for external op-amps in many applications |
| Low-power power-down mode | Reduces current to 80 nA @ 3 V - critical for always-on systems requiring ultra-low standby consumption |
| Automotive qualification | Qualified per AEC-Q100 Grade 2 (−40°C to +105°C) - suitable for engine control and ADAS subsystems |
Applications
| Portable Battery-Powered Instruments | Digital Gain and Offset Adjustment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad voltage-output DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5314BRMZ-REEL7 | Same 10-bit architecture and specs, but in 10-lead LFCSP (3 mm × 3 mm, thinner) instead of MSOP; identical pinout except exposed paddle replaces GND pin 7 | LFCSP offers better thermal performance and lower profile; requires different PCB land pattern and reflow profile | Select AD5314BRMZ-REEL7 for space-constrained or thermally demanding layouts; AD5314ARM-REEL7 preferred for legacy MSOP footprints |
| AD5324ARMZ-REEL7 | 12-bit resolution (vs. 10-bit), ±10 LSB INL (B version), higher supply current (700 μA typ @ 3 V), same package and interface | Used where higher precision is mandatory (e.g., medical instrumentation), accepting increased power and reduced noise margin | Choose AD5324ARMZ-REEL7 only when 12-bit resolution is required; AD5314ARM-REEL7 provides optimal balance of accuracy, power, and cost for general-purpose control |
Compared with AD5314BRMZ-REEL7, AD5314ARM-REEL7 offers identical electrical performance in a more widely adopted MSOP package; versus AD5324ARMZ-REEL7, it trades 2-bit resolution for 30% lower active current and tighter INL spec at mid-accuracy requirements.

FAQ
What is the guaranteed integral nonlinearity (INL) specification for AD5314ARM-REEL7?
The AD5314ARM-REEL7 B version guarantees ±2.5 LSB INL over the full operating temperature range (−40°C to +105°C). This specification is confirmed in the Rev. J datasheet Table 1 under DC Performance for AD5314, and applies directly to the AD5314ARM-REEL7 variant in MSOP packaging.
Does AD5314ARM-REEL7 support simultaneous update of all four DAC outputs?
Yes, AD5314ARM-REEL7 supports simultaneous output update via its LDAC (load DAC) function. When the LDAC pin is asserted (active low), all four DAC outputs change in unison, eliminating inter-channel timing skew and minimizing transient glitches in coordinated control applications.
What package type and dimensions does AD5314ARM-REEL7 use?
AD5314ARM-REEL7 uses a 10-lead MSOP (Mini Small Outline Package) with dimensions of 3.0 mm × 3.0 mm × 1.1 mm and an exposed thermal pad. Pin 1 is VDD; the exposed pad must be connected to GND for proper thermal and electrical performance, as specified in the Rev. J datasheet Figure 3 and Pin Function Descriptions.
Can AD5314ARM-REEL7 operate from a 2.5 V supply?
Yes, AD5314ARM-REEL7 is fully specified to operate from 2.5 V to 5.5 V. At 2.5 V, it draws 500–700 μA in normal mode and 80–100 nA in power-down mode, maintaining rail-to-rail output swing (0 V to 2.5 V) and full functionality including serial interface and power-on reset.
Is AD5314ARM-REEL7 qualified for automotive applications?
Yes, AD5314ARM-REEL7 is qualified for automotive applications per AEC-Q100 Grade 2 standards, supporting operation from −40°C to +105°C. This qualification is explicitly stated in the "Automotive Products" section of the Rev. J datasheet and applies to all AD5314 variants including the ARM-REEL7 MSOP package.
