LTC1604IG#TR

Updated: 2026-09-20

Overview

The LTC1604IG#TR is a 16-bit analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices). It is designed for high-precision applications requiring fast conversion rates and low power consumption. This IC is particularly suited for industrial measurement equipment, medical instrumentation, and communication systems where accurate signal acquisition is critical. The device operates with a single 5V supply and features a parallel interface for easy integration with microprocessors.

Structure and Working Principle

The LTC1604IG#TR utilizes a successive approximation register (SAR) architecture for analog-to-digital conversion. This design enables fast conversion times while maintaining high accuracy. The internal structure includes a sample-and-hold circuit, precision reference, and digital control logic. The device converts analog input voltages into 16-bit digital words at speeds up to 100 kSPS (kilo samples per second), making it suitable for dynamic signal acquisition applications.

Key Features

The LTC1604IG#TR offers several notable features including ±1 LSB (least significant bit) integral nonlinearity and ±1 LSB differential nonlinearity, ensuring high conversion accuracy. Additional features include low power consumption (typically 75mW), wide input voltage range, and flexible power-down modes. The device is available in a 28-pin SSOP package, suitable for space-constrained applications.

Application Areas

This IC is widely used in precision measurement systems such as industrial process control, medical imaging equipment, and scientific instrumentation. Other common applications include data acquisition systems, automatic test equipment, and communication infrastructure where high-resolution analog signal processing is required. The device's performance characteristics make it particularly valuable in applications demanding both speed and accuracy.

Maintenance and Precautions

Proper handling of the LTC1604IG#TR requires attention to ESD (electrostatic discharge) protection measures during installation and maintenance. The device should be stored in anti-static packaging when not in use. For optimal performance, designers should pay careful attention to PCB layout, particularly for the analog input and reference voltage sections. Adequate power supply decoupling is essential to maintain signal integrity in high-speed applications.

B2B Procurement Guide

When sourcing the LTC1604IG#TR, buyers should verify the manufacturer's part number and packaging (tape and reel) designation. The #TR suffix indicates tape and reel packaging for automated assembly. Consider lead times and minimum order quantities when planning purchases. For prototype quantities, authorized distributors may be preferable, while larger production runs might benefit from direct manufacturer engagement or specialized electronic component brokers.
