Product details
Overview
LTC2633HTS8-HI8#TRMPBF from Analog Devices is a dual 8-bit I²C voltage-output DAC with integrated 10ppm/°C 4.096V reference, rail-to-rail output buffers, and guaranteed monotonicity over –40°C to 125°C. It operates from 4.5V to 5.5V, delivers ±0.5LSB DNL, 3.7µs settling time (±1LSB), and supports both standard (100kHz) and fast-mode (400kHz) I²C. Used in automotive power supply margining and industrial sensor calibration.
For engineers reviewing the LTC2633HTS8-HI8#TRMPBF datasheet, LTC2633HTS8-HI8#TRMPBF pinout, LTC2633HTS8-HI8#TRMPBF application, or LTC2633HTS8-HI8#TRMPBF equivalent, key selection criteria include its H-grade automotive temperature range, internal 4.096V reference accuracy, mid-scale power-on reset behavior, and TSOT-23-8 package compatibility with space-constrained PCB layouts.
Technical Context
The LTC2633HTS8-HI8#TRMPBF implements two independent 8-bit DAC cores sharing a single high-stability internal reference and I²C interface. Its double-buffered registers prevent output glitches during simultaneous updates, and the internal reference switch enables seamless transition between internal (4.096V) and external reference modes without external circuitry.
Power-on reset is configured for mid-scale output in internal reference mode, ensuring predictable startup behavior in closed-loop control systems. The device uses rail-to-rail output amplifiers capable of sourcing/sinking up to ±48mA, with low 0.09Ω DC output impedance and 1.0V/µs slew rate-enabling direct drive of moderate capacitive loads up to 500pF.

FAQ
What is the full-scale output voltage of the LTC2633HTS8-HI8#TRMPBF when using the internal reference?
The LTC2633HTS8-HI8#TRMPBF delivers a 4.096V full-scale output voltage when operating in internal reference mode. This value is derived from the internal 2.048V reference (half-scale) and is specified over the full –40°C to 125°C temperature range with ±10ppm/°C drift, making it ideal for applications requiring tight voltage matching to common ADC reference standards.
Does the LTC2633HTS8-HI8#TRMPBF support fast-mode I²C communication?
Yes, the LTC2633HTS8-HI8#TRMPBF supports I²C fast-mode operation up to 400kHz. This allows rapid configuration and streaming updates without CPU bottlenecks, especially valuable in real-time control loops. The device also supports standard-mode (100kHz) for compatibility with legacy controllers, and all timing parameters-including tHD(DAT), tSU(DAT), and tLOW-are fully specified across the –40°C to 125°C range.
What is the power-on reset behavior of the LTC2633HTS8-HI8#TRMPBF?
The LTC2633HTS8-HI8#TRMPBF resets both DAC outputs to mid-scale (2.048V) when powered up in internal reference mode. This behavior is hard-coded by the "HI" suffix and eliminates output transients that could disrupt downstream circuitry-such as op-amp bias networks or motor driver enable paths-during system startup.
Can the LTC2633HTS8-HI8#TRMPBF operate with an external reference voltage?
Yes, the LTC2633HTS8-HI8#TRMPBF can operate with an external reference voltage applied to the REF pin. When external mode is selected, the full-scale output becomes equal to the applied VREF (1V ≤ VREF ≤ VCC). In this configuration, the internal reference is disabled, and the REF pin functions solely as an input-allowing flexible full-scale scaling for applications requiring non-standard output ranges.
What is the maximum output current capability of the LTC2633HTS8-HI8#TRMPBF?
The LTC2633HTS8-HI8#TRMPBF can source or sink up to ±48mA per output (VOUTA or VOUTB) when shorted to GND or VCC at VFS = VCC = 5.5V. This robust drive strength enables direct interfacing with moderate loads such as LED drivers, small solenoids, or op-amp input stages without external buffering-reducing component count and board area.
