Product details
Overview
LTC2626IDD-1#TRPBF from Analog Devices is a 12-bit rail-to-rail voltage-output DAC with I²C interface, operating from 2.7V to 5.5V supply. It delivers ±15mA output drive, ±0.5 LSB DNL, and 7µs settling time to ±1 LSB. Designed for precision analog control in industrial instrumentation and automated test equipment, it features power-on reset to mid-scale and double-buffered data latches.
For engineers reviewing the LTC2626IDD-1#TRPBF datasheet, LTC2626IDD-1#TRPBF pinout, LTC2626IDD-1#TRPBF application, or LTC2626IDD-1#TRPBF equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for embedded control and calibration systems.
Technical Context
The LTC2626IDD-1#TRPBF implements a 12-bit monotonic DAC core with integrated rail-to-rail output buffer and internal reference input path. Its I²C interface supports standard (100kHz) and fast mode (400kHz) clocking, with 27 selectable slave addresses via CA0–CA2 pins.
Power-on behavior is defined by the "-1" suffix: outputs initialize to mid-scale (2048/4095) and remain there until first valid write-and-update sequence. The LDAC pin enables asynchronous DAC register update independent of I²C transaction completion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12 bits - defines 4096 discrete output levels across full-scale range |
| Differential Nonlinearity | ±0.5 LSB - guarantees monotonicity and prevents code skipping in closed-loop control |
| Settling Time | 7 µs to ±1 LSB - enables rapid step response in dynamic calibration sequences |
| Output Drive | ±15 mA min - directly drives 66Ω loads at 1V headroom or 2kΩ+ instrumentation inputs |
| Supply Current | 270 µA at 3V - supports low-power portable and battery-backed systems |
| Power-Down Current | 1 µA max - reduces system standby power without losing register state |
| I²C Clock Rate | 400 kHz - allows 2.5 ms worst-case 3-byte write + update cycle for high-throughput control |
Pinout & Package
Package: 10-lead (3mm × 3mm) plastic DFN with exposed pad (Pin 11), rated for –40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LDAC (Pin 10) | Asynchronous DAC update enable | Falling edge triggers immediate transfer from input register to DAC register; required for synchronized multi-DAC updates |
| VOUT (Pin 7) | Analog voltage output | Rail-to-rail output stage delivers 0V to VREF range with ±15mA sourcing/sinking capability |
| REF (Pin 6) | Reference voltage input | Accepts 0V to VCC; sets full-scale output range; high-impedance (≥88 kΩ) input minimizes loading on external references |
| GND (Pin 8) | Analog ground | Primary return path for DAC core and output buffer; must be connected to low-noise system ground plane |
| VCC (Pin 9) | Positive supply | 2.7V–5.5V operation; powers DAC core, I²C interface, and output buffer; PSR = –81 dB suppresses supply noise |
| SCL / SDA (Pins 3, 2) | I²C serial clock/data | Standard-compliant open-drain interface; requires external pull-ups; supports 400kHz fast-mode timing |
| CA0–CA2 (Pins 4, 5, 1) | I²C address select inputs | Each pin configurable as VCC/GND/floating → 27 unique slave addresses for multi-device bus topology |
Key Features
| Feature | Design Value |
|---|---|
| Power-on reset to mid-scale | Initial output = 2048/4095 code eliminates startup transients in bias-sensitive circuits (e.g., op-amp offset calibration) |
| Double-buffered data latches | Input register accepts new data while DAC register holds previous value - enables glitch-free updates during continuous streaming |
| 27 selectable I²C addresses | Three address pins (CA0–CA2) support flexible multi-DAC configurations without address conflicts on shared buses |
| Rail-to-rail output drive | ±15mA minimum output current maintains linearity across full 0V–VREF range, even under 2kΩ load |
| Low-glitch architecture | 12 nV·s mid-scale glitch impulse ensures minimal disturbance in precision sensor excitation or feedback paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP4725A0T-E/CH | 12-bit, I²C, VDD=2.7–5.5V, but no LDAC pin; power-on reset to zero scale; ±2 LSB INL | Lacks asynchronous update and mid-scale boot - unsuitable for systems requiring deterministic startup bias | Select when board space is constrained (SOT-23-6) and LDAC synchronization is unnecessary |
| AD5620BRMZ-1 | 12-bit, SPI interface, VDD=2.7–5.5V, power-on reset to midscale, ±0.5 LSB DNL, but no I²C support | Requires SPI host controller; incompatible with I²C-only microcontrollers or FPGAs | Choose when higher noise immunity (SPI vs I²C) or tighter gain tempco (±3 ppm/°C vs ±8.5 ppm/°C) is critical |
Compared with MCP4725A0T-E/CH and AD5620BRMZ-1, the LTC2626IDD-1#TRPBF uniquely combines I²C compatibility, mid-scale power-on reset, and LDAC-triggered synchronous updates - essential for deterministic multi-channel calibration in industrial and medical systems.

FAQ
What is the power-on behavior of the LTC2626IDD-1#TRPBF?
The LTC2626IDD-1#TRPBF initializes its output to mid-scale (2048/4095) upon power application and holds that level until the first valid I²C write-and-update command or LDAC-triggered update occurs. This behavior is guaranteed by the "-1" suffix and eliminates startup transients in bias-critical circuits like op-amp offset calibration networks.
Does the LTC2626IDD-1#TRPBF support true rail-to-rail output swing?
Yes, the LTC2626IDD-1#TRPBF delivers rail-to-rail output voltage swing from 0V to VREF with ±15mA sourcing/sinking capability. Under 2kΩ load, it maintains linearity across the full range with ≤0.125 LSB/mA load regulation error - enabling direct drive of instrumentation amplifiers and reference buffers without external op-amps.
How many I²C addresses does the LTC2626IDD-1#TRPBF support?
The LTC2626IDD-1#TRPBF supports 27 unique I²C slave addresses via three configurable address pins (CA0, CA1, CA2), each settable to VCC, GND, or floating. This enables up to 27 LTC2626IDD-1#TRPBF devices on a single I²C bus without address conflict - ideal for multi-channel calibration systems.
What is the role of the LDAC pin on the LTC2626IDD-1#TRPBF?
The LDAC pin on the LTC2626IDD-1#TRPBF provides asynchronous DAC register update: a falling edge immediately transfers data from the input register to the DAC register and updates the analog output. This enables synchronized updates across multiple LTC2626IDD-1#TRPBF devices sharing the same I²C bus, critical for phase-aligned stimulus generation.
Can the LTC2626IDD-1#TRPBF operate from a 3V supply?
Yes, the LTC2626IDD-1#TRPBF operates from 2.7V to 5.5V supply. At 3V, it draws 270µA typical supply current, achieves 7µs settling time, and maintains ±0.5 LSB DNL performance. Its reference input accepts 0V to 3V, allowing direct use of internal LDOs or low-voltage bandgap references in portable designs.
