Product details
Overview
LTC2633CTS8-HI10#TRMPBF from Analog Devices is a dual 10-bit I²C voltage-output DAC with integrated 4.096V ±10ppm/°C reference, rail-to-rail output buffers, and guaranteed monotonicity over –40°C to 125°C. It operates from 4.5V to 5.5V, delivers ±1LSB INL (max), 3.7µs settling time, and supports I²C standard/fast mode up to 400kHz - used in precision power supply margining and automotive sensor calibration.
For engineers reviewing the LTC2633CTS8-HI10#TRMPBF datasheet, LTC2633CTS8-HI10#TRMPBF pinout, LTC2633CTS8-HI10#TRMPBF application, or LTC2633CTS8-HI10#TRMPBF equivalent, key selection criteria include internal 4.096V reference accuracy, H-grade temperature range, mid-scale power-on reset behavior, and TSOT-23-8 package compatibility with space-constrained industrial control modules.
Technical Context
The LTC2633CTS8-HI10#TRMPBF implements two independent 10-bit DAC channels sharing a single I²C interface and internal reference. Its double-buffered registers prevent output glitches during multi-byte writes, and the internal reference switch allows seamless transition between internal (4.096V) and external reference modes without external circuitry.
Power-on reset defaults to mid-scale output (2.048V per channel) when internal reference is active. The device incorporates input filtering to suppress spikes ≤50ns and guarantees monotonic operation across its full –40°C to 125°C automotive temperature range, with load regulation of 0.022 LSB/mA at 5V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - delivers 1024 discrete output levels with ±1LSB integral nonlinearity error. |
| Reference Voltage | 4.096V internal - enables precise 0–4.096V rail-to-rail output span without external reference component. |
| Temperature Range | –40°C to 125°C - qualified for under-hood automotive and industrial environments requiring extended thermal stability. |
| Settling Time | 3.7µs to ±1LSB - ensures fast response for closed-loop feedback control in real-time power management systems. |
| I²C Speed | Up to 400kHz - supports high-throughput configuration in multi-DAC systems with minimal bus overhead. |
| Supply Range | 4.5V to 5.5V - matches standard 5V system rails while maintaining specified performance across voltage tolerance. |

Pinout & Package
Package: 8-lead TSOT-23 (Thin Small Outline Transistor), 3mm × 1.7mm footprint, 0.65mm pitch, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SCL (Pin 1) | I²C clock input | Accepts 0–400kHz clock; requires external pull-up to VCC; defines data sampling edge (rising). |
| CA0 (Pin 2) | I²C address bit 0 | Selects one of four slave addresses (GND/VCC/floating); enables multiple DACs on same bus. |
| REF (Pin 3) | Reference I/O | Outputs 2.048V (half-scale) internal reference; accepts 1V–VCC external reference for custom full-scale. |
| GND (Pin 4) | Analog/digital ground | Common return path for reference, DAC outputs, and digital logic; must be low-impedance. |
| VOUTA (Pin 5) | DAC A analog output | Rail-to-rail buffered voltage output (0–4.096V); drives ≥2kΩ loads with <0.156Ω DC impedance. |
| VOUTB (Pin 6) | DAC B analog output | Independent rail-to-rail output identical to VOUTA; enables dual-channel control without external mux. |
| VCC (Pin 7) | Positive supply | 4.5–5.5V input; requires 0.1µF ceramic bypass capacitor placed near pin for noise suppression. |
| SDA (Pin 8) | I²C bidirectional data | Open-drain output during ACK; high-impedance input during data reception; needs pull-up resistor. |

FAQ
What is the full-scale output voltage of the LTC2633CTS8-HI10#TRMPBF?
The LTC2633CTS8-HI10#TRMPBF features an integrated 4.096V reference, resulting in a full-scale output voltage of 0V to 4.096V for both DAC channels when operating in internal reference mode. This value is factory-trimmed and specified with ±10ppm/°C temperature coefficient over –40°C to 125°C, ensuring stable scaling without external components.
Does the LTC2633CTS8-HI10#TRMPBF support external reference operation?
Yes, the LTC2633CTS8-HI10#TRMPBF supports external reference mode via the REF pin (Pin 3). When configured for external reference, the DAC full-scale output equals the applied voltage (1V ≤ VREF ≤ VCC), enabling flexible scaling for applications requiring non-standard output ranges. Internal reference remains disabled in this mode.
What is the power-on reset behavior of the LTC2633CTS8-HI10#TRMPBF?
The LTC2633CTS8-HI10#TRMPBF resets to mid-scale (2.048V) on power-up when internal reference mode is active - consistent with its "HI" and "I" suffix designation. This behavior provides a known, safe output state for analog control loops, avoiding transient overdrive or undervoltage conditions during system initialization.
Can the LTC2633CTS8-HI10#TRMPBF operate from a 3.3V supply?
No, the LTC2633CTS8-HI10#TRMPBF requires a minimum supply voltage of 4.5V due to its 4.096V internal reference architecture. Operation below 4.5V is outside specification and may result in degraded reference accuracy, reduced output drive capability, or failure to meet monotonicity guarantees across temperature.
How many unique I²C addresses does the LTC2633CTS8-HI10#TRMPBF support?
The LTC2633CTS8-HI10#TRMPBF supports four unique I²C slave addresses via the CA0 pin (Pin 2), which can be tied to GND, VCC, left floating, or pulled through a resistor. This allows up to four devices on the same bus without address conflict - essential for multi-channel calibration systems in automotive ECUs and industrial PLCs.
