Product details
Overview
AD5300BRM-REEL from Analog Devices is a single 8-bit buffered voltage-output DAC in an 8-lead MSOP package, operating from 2.7 V to 5.5 V with rail-to-rail output swing, 140 µA typical supply current at 5 V, and 4 µs half-scale settling time. It serves as a precision programmable voltage source in portable instrumentation requiring low-power, stable analog output generation.
For engineers reviewing the AD5300BRM-REEL datasheet, AD5300BRM-REEL pinout, AD5300BRM-REEL application, or AD5300BRM-REEL equivalent, key selection criteria include its micropower operation (200 nA power-down current), SPI-/QSPI-/MICROWIRE-compatible 3-wire serial interface up to 30 MHz, and internal power-supply-derived reference enabling full-scale output range of 0 V to VDD.
Technical Context
The AD5300BRM-REEL implements a resistor-string DAC architecture with on-chip rail-to-rail output buffer amplifier (1 V/µs slew rate) and no external reference required-VDD directly defines full-scale range. Its 16-bit serial input register includes 2 control bits for three software-selectable power-down modes (1 kΩ, 100 kΩ, or high-Z output termination) plus normal operation.
Power-on reset ensures DAC output powers up to 0 V and remains there until first valid write. SYNC interrupt capability allows early termination of serial writes, and Schmitt-triggered digital inputs support robust interfacing across voltage domains (VIH = 2.4 V min at VDD = 5 V; VIH = 2.1 V min at VDD = 3 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - delivers 256 discrete output levels with guaranteed monotonicity by design. |
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into 3.3 V and 5 V systems without level-shifting. |
| Output Voltage Range | 0 V to VDD - rail-to-rail swing maximizes dynamic range when referenced to system supply. |
| Settling Time | 4 µs (typ) - supports update rates up to ~250 kSPS for moderate-speed closed-loop control. |
| Power-Down Current | 200 nA @ 5 V / 50 nA @ 3 V - extends battery life in sleep-mode portable devices. |
| Serial Interface Speed | Up to 30 MHz SCLK - compatible with high-speed DSPs and microcontrollers using SPI/QSPI/MICROWIRE protocols. |
| Differential Nonlinearity | ±0.25 LSB - ensures monotonic response critical for feedback control and calibration applications. |
| Relative Accuracy | ±1 LSB - provides predictable end-point error for gain/offset trimming without per-unit calibration. |
Pinout & Package
AD5300BRM-REEL is housed in an 8-lead MSOP (RM-8) package with exposed pad (thermal performance θJA = 206°C/W). Pin 1 is marked; pins 2 and 3 are no-connect (NC). All digital inputs feature Schmitt-triggering for noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 3) | Analog output node | Rail-to-rail buffered voltage output; capable of sourcing/sinking 20 mA @ 3 V or 50 mA @ 5 V into resistive loads. |
| GND (Pin 8) | Analog/digital ground reference | Single ground connection point; requires low-impedance layout to minimize noise coupling into DAC output. |
| VDD (Pin 1) | Power supply and reference source | Supplies core logic and defines full-scale output range; must be bypassed with 10 µF + 0.1 µF capacitors near the pin. |
| SYNC (Pin 7) | Frame synchronization input (active low) | Initiates serial write sequence; rising edge before 16th SCLK falling edge aborts update (SYNC interrupt). |
| SCLK (Pin 6) | Serial clock input | Falling-edge–triggered; supports up to 30 MHz operation; timing validated across full VDD and temperature range. |
| DIN (Pin 5) | Serial data input | MSB-first 16-bit frame: bits DB15–DB14 (don't care), DB13–DB12 (power-down mode), DB11–DB4 (8-bit DAC data), DB3–DB0 (don't care). |
| NC (Pins 2, 3) | No connect | Not internally bonded; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress. |
Key Features
| Feature | Design Value |
|---|---|
| Power-supply–derived reference | Eliminates need for external voltage reference IC, reducing BOM count and board area in space-constrained designs. |
| Three software-selectable power-down modes | Enables precise control over output impedance during sleep: 1 kΩ or 100 kΩ to GND, or high-Z-critical for multiplexed analog backplanes. |
| Rail-to-rail output buffer with 1 V/µs slew rate | Delivers fast, distortion-free step responses into 2 kΩ || 1000 pF loads-suitable for driving ADC reference inputs or op-amp summing nodes. |
| Guaranteed monotonicity and ±1 LSB INL | Ensures predictable transfer function for closed-loop systems where nonmonotonic behavior could cause instability or oscillation. |
| Power-on reset to 0 V | Provides known safe output state at power-up-essential for biasing circuits or preventing transient glitches in sensitive analog signal paths. |
| Schmitt-triggered digital inputs | Accepts slow or noisy logic edges without false triggering; supports reliable communication across mixed-voltage interfaces (e.g., 1.8 V MCU to 5 V DAC). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit voltage-output DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5301BRM-REEL | Same 8-bit resolution and MSOP-8 package, but includes internal 2.5 V reference (REFIN/REFOUT pins); requires external decoupling for reference pin. | Better suited for systems needing fixed reference independence from VDD; less suitable when VDD is clean and preferred as reference. | Select AD5301BRM-REEL if reference stability must be isolated from supply ripple; otherwise AD5300BRM-REEL reduces component count. |
| MCP4725A0T-E/CH | I²C interface (not SPI), 12-bit resolution, internal EEPROM for power-on default code; VDD range 2.7 V–5.5 V, 140 µA typical current. | Preferred for I²C-based microcontrollers with limited GPIO; EEPROM enables "set-and-forget" configuration without host initialization. | Choose MCP4725A0T-E/CH for I²C ecosystems or when nonvolatile output retention is required; AD5300BRM-REEL offers faster interface and lower glitch energy. |
Compared with AD5301BRM-REEL and MCP4725A0T-E/CH, AD5300BRM-REEL provides the lowest digital feedthrough (0.5 nV·s) and fastest serial interface (30 MHz), making it optimal for noise-sensitive, high-throughput analog control loops where VDD is sufficiently stable to serve as reference.

FAQ
What is the maximum clock frequency supported by the AD5300BRM-REEL serial interface?
The AD5300BRM-REEL supports SCLK frequencies up to 30 MHz when VDD is 3.6 V to 5.5 V, and up to 20 MHz when VDD is 2.7 V to 3.6 V. These limits are specified across the full industrial temperature range (–40°C to +105°C) and ensure reliable data capture with defined setup/hold times (t5 = 5 ns, t6 = 4.5 ns). The interface remains functional beyond these rates but without guaranteed timing margin.
Does the AD5300BRM-REEL require an external reference voltage?
No, the AD5300BRM-REEL does not require an external reference. Its reference is derived directly from the VDD supply, enabling a full-scale output range of 0 V to VDD. This eliminates the need for external reference ICs or precision resistors, simplifying design and reducing cost-provided the VDD rail is sufficiently stable and low-noise for the target application.
How does the power-on reset function in the AD5300BRM-REEL?
The AD5300BRM-REEL incorporates an internal power-on reset circuit that forces the DAC register to zero and holds VOUT at 0 V until the first valid 16-bit serial write completes. This behavior is guaranteed across all VDD ramp rates and ensures a known, safe output state during system startup-critical for preventing unintended actuator movement or amplifier saturation in control systems.
What are the three power-down modes of the AD5300BRM-REEL and how are they selected?
The AD5300BRM-REEL offers three power-down modes selected via bits DB13 and DB12 in the 16-bit serial command: "01" configures 1 kΩ to GND, "10" configures 100 kΩ to GND, and "11" places VOUT in high-impedance (three-state). These modes reduce supply current to 200 nA @ 5 V and provide defined output termination-enabling predictable behavior in multiplexed or shared analog buses.
Can the AD5300BRM-REEL drive capacitive loads, and what is its stability limit?
Yes, the AD5300BRM-REEL's output buffer is stable driving capacitive loads up to 470 pF with no load resistance (RL = ∞) and up to 1000 pF when RL = 2 kΩ. This is verified in the datasheet (Figure 16) and enables direct connection to sampling capacitors, ADC reference inputs, or long traces without external isolation resistors-reducing component count and phase lag in feedback paths.
