Product details
Overview
LTC2637CMS-HMX10#PBF from Analog Devices is an octal 10-bit voltage-output DAC with integrated 4.096V ±10ppm/°C precision reference, rail-to-rail output buffers, and I²C interface. It operates from 4.5V to 5.5V, guarantees monotonicity over –40°C to 125°C, and delivers ±1LSB INL and ultralow DAC-to-DAC crosstalk (<3nV·s) for high-channel-density industrial control systems.
For engineers reviewing the LTC2637CMS-HMX10#PBF datasheet, LTC2637CMS-HMX10#PBF pinout, LTC2637CMS-HMX10#PBF application, or LTC2637CMS-HMX10#PBF equivalent, key selection criteria include its external-reference operation mode, H-grade automotive temperature range, MSOP-16 package, 400kHz I²C fast-mode support, and mid-scale power-on reset behavior.
Technical Context
The LTC2637CMS-HMX10#PBF implements eight independent 10-bit DAC channels sharing a single I²C bus with configurable slave address via CA0–CA2 pins. Its internal architecture includes double-buffered data latches, a dedicated power-on reset circuit that forces all outputs to mid-scale when using an external reference, and a precision reference switch enabling seamless transition between internal (4.096V) and external reference sources.
It features rail-to-rail output drivers capable of sourcing/sinking ±10mA (at VCC = 5V), low-noise performance (0.1Hz–200kHz: 750µVP-P), and guaranteed monotonicity across the full automotive temperature range. The device supports both standard (100kHz) and fast-mode (400kHz) I²C timing, with tSU(DAT) ≥ 100ns and tHD(DAT) ≤ 0.9µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - delivers 1024 discrete output levels with ±1LSB integral nonlinearity error. |
| Reference Mode | External reference - full-scale output equals applied VREF (1V to VCC), enabling flexible scaling in closed-loop systems. |
| Power-On Reset | Mid-scale in external reference mode - ensures predictable startup state without software initialization. |
| Supply Range | 4.5V to 5.5V - compatible with 5V industrial and automotive power rails; excludes lower-voltage operation. |
| I²C Speed | Up to 400kHz - supports fast configuration updates in real-time control loops without bus contention. |
| Temperature Range | –40°C to +125°C - qualified for under-hood automotive and harsh industrial environments. |
| Output Crosstalk | <3nV·s - prevents signal corruption during simultaneous channel updates in multi-axis motion control. |
Pinout & Package
Package: 16-lead MSOP (4mm × 5mm), exposed pad not present (DFN-only has exposed pad). Pin 16 is GND; no thermal pad soldering requirement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Positive supply input | 4.5V–5.5V only; requires local 0.1µF bypass capacitor to GND for noise immunity. |
| VOUTA–VOUTD (Pins 2–5) | Analog voltage outputs | Four of eight DAC outputs; rail-to-rail buffered, capable of ±10mA drive at 5V. |
| CA0 (Pin 7) | I²C address bit 0 | Configurable logic level (VCC/GND/floating) to select one of eight possible I²C addresses. |
| SCL (Pin 8) | I²C clock input | Open-drain compatible; requires external pull-up to VCC; supports 400kHz fast-mode timing. |
| SDA (Pin 9) | I²C bidirectional data | Open-drain; shares bus with other I²C peripherals; acknowledges writes with low pulse. |
| REF (Pin 11) | Reference input/output | In external mode: accepts 1V–VCC; sets full-scale output; must be stable and low-noise. |
| VOUTE–VOUTH (Pins 12–15) | Analog voltage outputs | Remaining four DAC outputs; electrically identical to VOUTA–D; share same specs and drive capability. |
| GND (Pin 16) | Ground reference | Primary return path for analog and digital currents; must connect to low-impedance system ground plane. |
| CA1 (Pin 10) | I²C address bit 1 | MSOP-only pin; used with CA0 and CA2 to configure full 3-bit I²C address (see Table 1). |
| CA2 (Pin 6) | I²C address bit 2 | MSOP-only pin; enables up to eight LTC2637 devices on same I²C bus without address conflict. |
Key Features
| Feature | Design Value |
|---|---|
| Octal 10-bit DAC integration | Reduces board space and BOM count vs. eight discrete DACs; eliminates inter-channel timing skew. |
| External reference operation (HMX variant) | Enables precise full-scale matching to system reference (e.g., 2.5V, 3.3V, or 5V rails) without gain calibration. |
| Mid-scale power-on reset | Prevents transient output spikes during power-up in safety-critical applications like valve control or sensor biasing. |
| Ultralow DAC-to-DAC crosstalk (<3nV·s) | Maintains signal integrity in tightly coupled systems such as optical transceiver bias control or multi-channel ADC reference trimming. |
| Rail-to-rail output buffer | Delivers full dynamic range from 0V to VCC, simplifying interface to op-amps, comparators, or actuator drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-output DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5667RBRMZ-5REEL7 | Octal 16-bit DAC with internal 2.5V reference; SPI interface; 2.7–5.5V supply; no external reference mode. | Higher resolution but fixed internal reference limits full-scale flexibility; SPI requires additional GPIO vs. I²C shared bus. | Select when absolute precision >12-bit is required and external reference scaling is unnecessary. |
| MCP4728-E/UN | Octal 12-bit DAC with internal 2.048V reference; I²C interface; 2.7–5.5V supply; reset-to-zero-scale only. | Lacks external reference option and automotive temperature grade; higher INL (±4LSB) and no H-grade qualification. | Select for cost-sensitive commercial-grade applications where 12-bit resolution suffices and external reference is not needed. |
Compared with AD5667RBRMZ-5REEL7 and MCP4728-E/UN, the LTC2637CMS-HMX10#PBF uniquely combines external reference support, automotive temperature qualification, and mid-scale power-on reset-enabling robust, scalable analog output design in safety-critical embedded systems without layout or firmware redesign.

FAQ
What is the full-scale output voltage range of the LTC2637CMS-HMX10#PBF?
The LTC2637CMS-HMX10#PBF operates in external reference mode, so its full-scale output voltage equals the voltage applied to the REF pin (1V to VCC). With VCC = 5.5V, full-scale spans 1V to 5.5V. It does not use the internal 4.096V reference-this variant is specifically configured for external reference operation per the "HMX" suffix.
Does the LTC2637CMS-HMX10#PBF support I²C fast-mode operation?
Yes, the LTC2637CMS-HMX10#PBF supports I²C fast-mode operation up to 400kHz, with guaranteed timing parameters including tSU(DAT) ≥ 100ns and tHD(DAT) ≤ 0.9µs across –40°C to +125°C. This enables rapid configuration of all eight DAC channels in time-critical control loops.
What is the power-on reset behavior of the LTC2637CMS-HMX10#PBF?
The LTC2637CMS-HMX10#PBF performs a mid-scale power-on reset when operating in external reference mode, as indicated by the "MX" suffix. At power-up, all eight DAC outputs settle to code 512 (mid-scale of 10-bit range), ensuring safe, known initial conditions without software intervention.
Can the LTC2637CMS-HMX10#PBF drive capacitive loads, and what is the maximum supported value?
Yes, the LTC2637CMS-HMX10#PBF can drive capacitive loads up to 500pF while maintaining specified settling time (≤5µs to ±1LSB). For larger loads, external buffering is recommended. The internal reference output (when enabled) supports up to 10µF, but this does not apply to the DAC outputs in HMX mode.
Is the LTC2637CMS-HMX10#PBF qualified for automotive applications?
Yes, the LTC2637CMS-HMX10#PBF carries the "H" temperature grade, meaning it is fully specified and tested from –40°C to +125°C and qualified per AEC-Q100 for automotive applications. Its MSOP-16 package and robust I²C interface make it suitable for engine control, ADAS sensor calibration, and body electronics.
