概述

Description

The TLC549CDR is a Texas Instruments 8‑bit, single‑ended successive‑approximation ADC in the TLC549 family. It converts an analog input to an 8‑bit digital word and provides a serial data output and a simple control interface, suitable for microcontroller or DSP front ends. Designed for low‑to‑moderate speed data acquisition on a single supply (typically 5V) with an optional external reference. The CDR suffix refers to the packaging variant (an 8‑pin device, tape & reel).
Key features:
- 8‑bit resolution; SAR architecture
- Serial (SPI‑like) interface
- Low power; small 8‑pin package
- External reference option
Typical applications:
- Sensors, basic data‑acquisition, instrumentation, embedded control
For exact electrical specs, timing diagrams, and pinout, consult the TLC549CDR datasheet.

Features

Here are concise features of the TLC549CDR (TI):
- 8-bit resolving DAC (256 steps)
- Multiplying DAC: full-scale set by external reference (0 to VREF)
- Single-supply operation: broad operating range (typical 2.7V–5.5V)
- Voltage output (0 to VREF)
- Monotonic performance with good linearity
- Low-power CMOS design
- 8-pin package (SOIC/DIP style as indicated by CDR suffix)
- Industrial temperature range (-40°C to 85°C) (typical for many TLC parts)
Note: for exact electrical specs (settling time, leakage, DNL, etc.), please consult the official datasheet.

Package

8-pin SOIC (D‑package) in Tape‑and‑Reel, Commercial temperature range.

Pinout

Pin count: 8 pins (SOIC-8/DIP-8).
Function: 8-bit analog-to-digital converter (SAR) with a serial (SPI-compatible) interface.

Manufacturer

Manufacturer: Texas Instruments (TI).
Company type: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits and related products.
