Descripción general

Description

The LTC2662IUH-12#PBF is Linear Technology (now Analog Devices) a 12‑bit, serial‑input, voltage‑output DAC (multiplying DAC family) in a Pb‑free IUH package. The “12” indicates 12‑bit resolution; “PBF” means Pb‑free; “IUH” is the package code.
Key points:
- Interface: SPI‑like serial control (data word + command) to set the DAC output.
- Output: Buffered voltage proportional to the reference input (external reference supplied externally).
- Features: Suitable for precision calibration, test equipment, instrumentation, and control loops; supports unipolar/bipolar ranges via reference configuration.
- Power and packaging: Designed for low power operation with a typical compact surface‑mount package (Pb‑free).
- Use: Provide supply (and reference), drive the serial lines from a microcontroller or FPGA, and buffer VOUT if needed for the application.
For exact pinout, timing, electrical specs (INL/DNL, settling time), and how to encode commands, consult the LTC2662U datasheet and application notes.

Features

Here are the key features of LTC2662IUH-12#PBF (concise):
- Dual 12-bit multiplying DACs (MDAC)
- SPI-compatible serial interface for control
- Current-output (Iout) DAC requiring an external op-amp
- External reference input to set full-scale (supports bipolar/unipolar ranges via Vref)
- Fast settling with low glitch energy
- Low power consumption; suitable for battery-powered designs
- Wide temperature range (industrial) for robustness
- RoHS-compliant, lead-free packaging (PBF)
Note: For exact electrical specs (voltages, currents, timing, and package details), please consult the LTC2662 datasheet.

Package

The LTC2662IUH-12#PBF comes in a 16-lead TSSOP (UH) package, Pb-free RoHS compliant.

Pinout

- Pin count: 16 pins (16‑lead package, IUH)
- Function: Dual 12‑bit digital‑to‑analog converter (DAC) with a serial (SPI‑like) interface. It provides two buffered voltage outputs (VOUTA, VOUTB) and includes standard control and reference pins (CS, SCLK, SDIN, LDAC/CLR, VREF, etc.).

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). It is a global American semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits; ADI acquired Linear Technology (the LTC line) in 2017.

Application

Possible application areas for LTC2662IUH-12#PBF:
- Multi-channel precision DAC for test equipment and data acquisition
- Programmable analog front-ends and calibration/trim networks
- Waveform generation and signal conditioning in lab benches
- Servo/motor control and automation systems
- Sensor excitation and multi-channel measurement arrays
- Audio/visual processing with per-channel gain/offset control
- Medical instrumentation and research/bench instrumentation

Equivalent

Direct cross-references (dual 12-bit DACs) from other vendors include:
- TI DAC8562 (dual 12-bit, voltage output, I2C)
- Analog Devices AD5662 (dual 12-bit, voltage output, I2C)
- Microchip MCP4922 (dual 12-bit, voltage output, SPI)
Note: interfaces (SPI/I2C), output type, references, and packaging differ. Use DigiKey/Mouser cross-reference tools to map -PBF IUH packaging to exact equivalents.
