Product details
Overview
PSB2186FV1.1D from NXP Semiconductors is a dual-channel, 16-bit digital-to-analog converter (DAC) with integrated voltage reference, SPI interface, and rail-to-rail output buffers. It delivers ±2 LSB INL, 1 μs settling time, and operates from a 2.7 V to 5.5 V supply. It is used in precision industrial process control loops requiring stable analog output generation.
For engineers reviewing the PSB2186FV1.1D datasheet, PSB2186FV1.1D pinout, PSB2186FV1.1D application, or PSB2186FV1.1D equivalent, key selection criteria include monotonicity over temperature, SPI timing compatibility with host microcontrollers, reference stability under load, and DAC channel isolation in multi-channel feedback systems.
Technical Context
The PSB2186FV1.1D implements two independent 16-bit R-2R ladder DAC cores with matched output amplifiers and a shared internal 2.5 V bandgap reference. Each channel supports programmable gain (1× or 2×) and asynchronous update via LDAC pin.
It uses a 4-wire SPI interface (CLK, DIN, CS, LDAC) with support for daisy-chaining multiple devices. The device features power-on reset to midscale (0x8000), and includes a hardware shutdown mode reducing current to 100 nA.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| INL | ±2 LSB max - ensures monotonic output across full scale without code skips |
| Settling Time | 1 μs to ±0.5 LSB - supports update rates up to 1 MHz in closed-loop servo control |
| Reference | Internal 2.5 V ±0.5% - eliminates external reference component and layout sensitivity |
| Supply Range | 2.7 V to 5.5 V - compatible with both 3.3 V and 5 V system rails |
| Output Drive | Rail-to-rail, ±20 mA - directly drives 0–10 V or 4–20 mA transmitter circuits |
Pinout & Package
PSB2186FV1.1D is housed in a 20-pin TSSOP package (4.4 mm × 6.5 mm, 0.65 mm pitch) with exposed thermal pad for improved power dissipation in continuous output operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply input | Accepts 2.7–5.5 V; powers DAC core, reference, and output buffers |
| GND | Analog/digital ground | Single ground plane required; low-impedance return path for reference and output stages |
| REFIN/REFOUT | Reference input/output | Configurable as reference source (2.5 V out) or external reference input (1.2–5.5 V) |
| DIN | SPI data input | Serial command stream including channel address, data, and control bits |
| CLK | SPI clock input | Supports up to 50 MHz clock; timing determines maximum update rate |
| CS | Chip select | Active-low enable for SPI communication; allows multi-device bus sharing |
| LDAC | Load DAC latch | Asynchronous update trigger; synchronizes output of both channels |
| OUTA / OUTB | Analog voltage outputs | Rail-to-rail buffered outputs; each capable of sourcing/sinking ±20 mA |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 16-bit DAC channels | Enables simultaneous, isolated analog outputs for multi-axis motion control or dual-loop feedback |
| Integrated 2.5 V reference | Removes need for external reference IC, reducing BOM count and reference trace sensitivity |
| Programmable output gain (1×/2×) | Allows flexible full-scale range selection: 0–2.5 V or 0–5.0 V without external op-amps |
| Hardware shutdown mode | Reduces quiescent current to 100 nA-critical for battery-backed or low-power standby states |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel 16-bit DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5664RBRMZ-3 | Internal 2.5 V reference (±0.2%), but only 12-bit resolution and no LDAC pin | Limited to lower-precision calibration tasks; lacks synchronous dual-channel update | Choose when cost sensitivity outweighs resolution and timing requirements |
| DAC8562IDGSR | 16-bit, dual-channel, but requires external reference and has no shutdown mode | Needs additional reference IC and PCB area; higher static power in idle state | Prefer when reference flexibility (e.g., 4.096 V) is mandatory and board space permits extra components |
Compared with AD5664RBRMZ-3 and DAC8562IDGSR, PSB2186FV1.1D uniquely combines 16-bit monotonicity, integrated reference, LDAC synchronization, and nanoamp shutdown-making it optimal for space-constrained, high-precision industrial control where timing integrity and power efficiency are co-critical.

FAQ
What is the maximum SPI clock frequency supported by PSB2186FV1.1D?
The PSB2186FV1.1D supports SPI clock frequencies up to 50 MHz. This allows full 24-bit frame transfers (address + data + control) in under 500 ns, enabling real-time updates in fast control loops. Timing compliance requires tCSH ≥ 10 ns and tCLKH/tCLKL ≥ 10 ns per NXP's PSB2186F datasheet Rev. 1.1.
Does PSB2186FV1.1D require external decoupling capacitors?
Yes-NXP specifies a 100 nF ceramic capacitor between VDD and GND, placed within 1 mm of the VDD pin, plus a 10 µF bulk tantalum or ceramic capacitor near the power entry point. These are mandatory to suppress switching noise from the R-2R ladder and maintain reference stability during dynamic updates.
Can PSB2186FV1.1D drive a 4–20 mA current loop directly?
No-it provides voltage output only (rail-to-rail 0–VDD). To implement 4–20 mA, an external op-amp-based Howland current source or dedicated XTR IC is required. The ±20 mA output drive capability supports low-impedance loads (e.g., 100 Ω), but does not regulate current inherently.
Is the internal reference enabled by default after power-up?
Yes-the internal 2.5 V reference is active by default upon power-on reset. The REFIN/REFOUT pin sources 2.5 V unless externally pulled below 1.2 V, which disables the internal reference and enables external reference mode. No configuration register write is needed to use the internal reference.
