Description

The LTC1668IG#TRPBF is Linear Technology (now Analog Devices) an 8-channel, 12-bit multiplexed ADC with a SPI‑compatible serial interface. It scans eight single-ended inputs via an internal multiplexer and delivers 12-bit digital results over the serial bus. It typically operates from a single supply and uses an external reference. Interface lines are CS, SCK, DIN, DOUT (in some variants). The IG suffix denotes industrial-grade Pb‑free device, and TRPBF means Tape‑and‑Reel packaging, Pb‑free. Applications include data acquisition, instrumentation, and multi-channel sensing. For exact electrical specs, timing, pinout, and packaging details, consult the LTC1668 datasheet and packaging guide.

Features

Here are the typical features of LTC1668IG#TRPBF (concise):
- 8-channel multiplexed input with a 12-bit SAR ADC
- SPI-compatible serial interface for digital data
- On-chip track-and-hold for sampling
- Internal reference option (and external reference input supported)
- Unipolar input range (0 to Vref); compatible with common reference levels
- Single-supply operation; typically 4.75V–5.25V
- Low power with power-down/ standby mode
- Monotonic conversion with predictable accuracy
- Data rate up to about 1 MSPS (aggregate rate; per-channel performance varies)
- Package: 28-pin device in standard package options; TRPBF indicates tape-and-reel packaging
Note: exact numbers (like voltage ranges, exact throughput) can vary by revision; consult the latest datasheet for precise specifications.

Package

28-pin TSSOP (Thin Shrink Small Outline Package), Pb-free, Tape & Reel packaging.

Pinout

- Pin count: 28 pins (LQFP/TSSOP package, depending on variant)
- Function: 8-channel, 12-bit ADC with a serial (SPI‑like) interface. It multiplexes eight analog inputs (AIN0–AIN7) to a 12-bit digital word, with external reference and separate analog/digital supplies; interface includes clock, chip/select, and serial data output.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI). The LTC1668 was originally from Linear Technology and is now part of Analog Devices (acquired Linear Technology in 2017).
- Company type: A global American semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits for various applications.

Application

Key application areas for LTC1668IG#TRPBF (multi‑channel ADC):
- Data acquisition and instrumentation (multi-channel measurement)
- Industrial automation and process control
- Automotive sensors and diagnostics
- Medical instrumentation and patient monitoring
- Portable/battery-powered test equipment
- Sensor front-ends for environmental monitoring
