概述

Description

The LTC1660IGN is Linear Technology’s (now Analog Devices) 8‑bit multiplying digital‑to‑analog converter (MDAC). It converts an 8‑bit digital input and a reference voltage into an analog output proportional to their product. The device typically provides a current output (Iout) that, with an external resistor or op amp, becomes a usable voltage; the full‑scale current is set by the reference and Rset. The “IGN” suffix denotes the specific package and temperature grade for this part (an 8‑pin package variant).
Key points:
- 8‑bit resolution MDAC for digitally controlled analog signals
- Multiplying behavior: output proportional to digital code × reference
- Usually used with an external op‑amp/resistor network to yield a voltage output
- Suitable for programmable gain, waveform generation, calibration, and control loops
- Features often include fast settling, low glitch, single‑supply operation, and modest power
For exact pinout, electrical specs, and interface details, consult the LTC1660 datasheet for the IGN package.

Features

LTC1660IGN features (concise):
- 12-bit multiplying DAC with voltage output
- Serial input (SPI-like) interface for digital data
- External reference input to set full-scale
- Single-supply operation from 2.7V to 5.25V
- Low power consumption
- Fast settling with guaranteed monotonicity
- 8-pin package (IGN suffix)
- Industrial temperature range (typical)

Package

LTC1660IGN comes in an 8-pin DIP package (DIP-8).

Pinout

- Pin count: 8 pins (in the -IGN package, typically 8-pin SOIC/DIP).
- Function: An 8-bit serial-input multiplying DAC with a current-output (Iout). It converts a digital word (with a reference) to a proportional output current, which is usually converted to voltage by an external op-amp.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). It is a global semiconductor company that designs and manufactures analog, mixed-signal, and DSP ICs. The LTC line (including LTC1660IGN) originated from Linear Technology, which was acquired by Analog Devices in 2017.

Application

Applications of LTC1660IGN include:
- Data acquisition systems and instrumentation front-ends needing analog signal multiplexing
- Sensor arrays and multiplexed measurements in industrial/automotive environments
- Portable/handheld medical and diagnostic devices
- Audio/video signal routing and conditioning
- Test and measurement equipment and lab instrumentation
