Tổng quan

Description

The LTC2614IGN#PBF is Linear Technology (now Analog Devices)’s 14‑bit digital‑to‑analog converter (DAC). It communicates via a serial, SPI‑like interface to program the DAC code for precise analogue output. The IGN suffix identifies the package variant, and #PBF indicates Pb‑free packaging. It’s aimed at precision analogue output in instrumentation, control, and test equipment.
Key takeaways:
- 14‑bit DAC with SPI-compatible control bus
- Pb‑free device in the IGN package
- Used for accurate analogue output in data acquisition, calibration, and control applications
For exact details (number of channels, output range, reference options, update rate, power supply, and timing), consult the LTC2614 datasheet. If you want, I can pull out the main specs and operation tips.

Equivalent

There isn’t an exact drop-in equivalent for LTC2614IGN#PBF. Closest options are 14-bit, 4-channel ADCs with SPI from other vendors (Analog Devices, TI, Maxim) with similar speed/interface. To provide precise cross‑refs, please share your required specs (sampling rate, input type, voltage range, package) or allow me to fetch current cross references.

Features

Here are the key features of LTC2614IGN#PBF (concise):
- Quad 16-bit voltage-output DAC with SPI-compatible serial interface
- Multiplying DAC (MDAC) architecture; full-scale range set by VREF (external reference supported; internal ref option)
- Simultaneous update capability via LDAC; monotonic 16-bit performance
- Fast settling with low glitch energy for clean step changes
- Wide supply range: typically 2.7V to 5.5V
- Industrial temperature range: −40°C to 85°C
- Low power operation; suitable for compact, battery-powered designs
- Pb-free, RoHS-compliant package (PBF) in a 28-pin package
Note: Exact package variant and pinout are as per the datasheet.

Pinout

- Pin count: 8 pins (8-pin package, e.g., MSOP/SOP).
- Function: Serial-input, voltage-output digital-to-analog converter (DAC) with SPI-compatible interface (CS/SCLK/DIN/LDAC, Vref/Vout/GND/Vdd).
