Product details
Overview
LTC1663IMS8#TRPBF from Analog Devices (formerly Linear Technology) is a 10-bit buffered rail-to-rail voltage-output DAC with 2-wire SMBus-compatible interface, operating from 2.7V to 5.5V single supply. It features selectable reference (internal 1.25V bandgap → 2.5V full-scale or VCC-ratiometric), 60μA typical operating current, and power-down mode drawing only 10μA. It delivers precise analog control in space-constrained industrial sensor conditioning and battery-powered instrumentation.
For engineers reviewing the LTC1663IMS8#TRPBF datasheet, LTC1663IMS8#TRPBF pinout, LTC1663IMS8#TRPBF application, or LTC1663IMS8#TRPBF equivalent, key selection criteria include its MSOP-8 package with user-configurable slave address (AD0–AD2), true rail-to-rail output swing (0V to VCC or 0V to 2.5V), ±0.75LSB max DNL, and guaranteed monotonicity over –40°C to +85°C.
Technical Context
The LTC1663IMS8#TRPBF integrates a double-buffered 10-bit DAC core, rail-to-rail output amplifier, and SMBus-compliant 2-wire serial interface with programmable command byte (BG/SD/SY bits). Its internal bandgap reference provides stable 2.5V full-scale output independent of supply variation, while VCC-ratiometric mode enables direct scaling with system rails.
It supports simultaneous multi-device update via STOP-triggered latch transfer or synchronous update using the dedicated 0x7E SYNC address. Address pins AD0–AD2 (pins 6, 2, 3) allow eight unique slave addresses in MSOP-8 packages-critical for dense SMBus node deployments without address conflict.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - 1024 discrete output levels across full-scale range |
| Output Span | 0V to VCC (ratiometric) or 0V to 2.5V (bandgap) - true rail-to-rail operation with no headroom loss |
| Differential Nonlinearity | ±0.75LSB max - guarantees monotonicity and prevents code skipping in closed-loop control |
| Supply Current | 60μA typ at 3V - enables >1-year battery life in low-duty-cycle portable instruments |
| Shutdown Current | 10μA max - preserves register state while minimizing quiescent drain during idle periods |
| Reference Select | Software-configurable via BG bit - eliminates external reference component when supply stability is insufficient |
| SMBus Frequency | 10kHz to 100kHz - compatible with legacy SMBus masters and low-speed microcontrollers |

| 4 (SCL) | Serial Clock Input | High-impedance clock input; rising edge clocks data; requires external pull-up |
| 5 (VOUT) | Analog Voltage Output | Buffered rail-to-rail output capable of sourcing/sinking ≥5mA; stable with ≤1000pF load |
| 6 (AD0) | Address Select Bit 0 | Third user-configurable address bit; completes 3-bit address field (AD2:AD0) |
| 7 (GND) | Analog/Digital Ground | Single ground reference for DAC core, interface, and output amplifier; no separate AGND/DGND |
| 8 (VCC) | Positive Supply & Reference | 2.7V–5.5V supply input; also serves as ratiometric reference when BG = 0 |
Key Features
| Feature | Design Value |
|---|---|
| Double-buffered data registers | Enables glitch-free simultaneous update of multiple LTC1663IMS8#TRPBF devices via shared STOP condition |
| Selectable reference source | Internal 1.25V bandgap (→ 2.5V FS) or VCC eliminates need for external precision reference in cost-sensitive designs |
| Power-on reset | Forces VOUT to 0V and clears all registers at power-up - prevents undefined output states during boot |
| 8-user-address capability | AD0–AD2 pins support 8 unique SMBus addresses in MSOP-8 package - simplifies multi-DAC bus topology |
| Rail-to-rail output amplifier | Drives 0V to VCC (or 0V to 2.5V) with <10mV rail margin; 85Ω output impedance ensures stability into 10kΩ//100pF loads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-output DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC1669CS5#TRPBF | Pin-compatible SOT-23-5 variant; fixed 7-bit address (0x40); no AD0–AD2 pins; identical electrical specs except 5-lead package limits routing density. | Best for ultra-compact single-DAC nodes where bus address flexibility is unnecessary and PCB area is premium. | Select LTC1669CS5#TRPBF when board space is constrained and only one DAC per bus segment is required. |
| LTC1659CMS8#TRPBF | 12-bit resolution, 3-wire SPI interface, multiplying architecture (REF input), higher ICC (120μA), no internal reference or SMBus support. | Suited for higher-precision applications needing >10-bit resolution and REF flexibility, but requires SPI host and external reference. | Choose LTC1659CMS8#TRPBF when 12-bit accuracy and REF independence outweigh SMBus compatibility and micropower needs. |
Compared with LTC1663IMS8#TRPBF, LTC1669CS5#TRPBF offers identical functionality in a smaller footprint but sacrifices address configurability, while LTC1659CMS8#TRPBF trades SMBus simplicity and 10μA shutdown for 12-bit precision and SPI flexibility - making each optimal for distinct system-level trade-offs.

FAQ
What is the operating temperature range for the LTC1663IMS8#TRPBF?
The LTC1663IMS8#TRPBF is specified for operation from –40°C to +85°C (I-grade), with full electrical performance guaranteed across this range including DNL, INL, and reference stability. This makes LTC1663IMS8#TRPBF suitable for deployment in harsh industrial environments without derating.
How does the reference selection work on the LTC1663IMS8#TRPBF?
The LTC1663IMS8#TRPBF uses the BG bit in the command byte to select reference: BG = 0 selects VCC (ratiometric output 0V to VCC), BG = 1 selects the internal 1.25V bandgap (fixed 2.5V full-scale output). This setting persists through power cycles and is independent of AD0–AD2 pin states.
Can the LTC1663IMS8#TRPBF drive capacitive loads?
Yes - the LTC1663IMS8#TRPBF output amplifier is stable driving capacitive loads up to 1000pF. For larger loads (e.g., 0.1μF), adding a small series resistor (e.g., 110Ω) restores phase margin to ≥45°, enabling robust operation in filter or cable-driving configurations without oscillation.
What is the purpose of the AD0, AD1, and AD2 pins on the LTC1663IMS8#TRPBF?
AD0, AD1, and AD2 are user-configurable address select pins that define the three LSBs of the LTC1663IMS8#TRPBF's 7-bit SMBus slave address. Combined with factory-programmed MSBs (0100), they enable eight unique addresses (0x40–0x47) on a single bus - essential for daisy-chained multi-DAC systems.
Does the LTC1663IMS8#TRPBF have power-on reset functionality?
Yes - the LTC1663IMS8#TRPBF incorporates hardware power-on reset that forces VOUT to 0V and clears all internal registers (including command and data latches) upon initial power application. This ensures a known, safe output state without requiring firmware initialization.
