TLC277CD

Description

The TLC277CD is a dual precision operational amplifier (op amp) from Texas Instruments, designed for high-performance applications. It features trimmed offset voltage, low noise, and high input impedance, making it suitable for precision amplification, sensor signal conditioning, and instrumentation systems. This op amp operates over a wide range of supply voltages and temperatures, with single-supply operation possible. Its common-mode input voltage range extends below the negative rail, allowing for flexibility in design. The TLC277CD also features ESD-protection circuitry and is designed-in latch-up immunity, making it suitable for automotive and industrial applications. With a small outline package (SOIC-8) and RoHS compliance, this op amp is ideal for use in a variety of applications, including audio signal processing, data acquisition, and control systems. Its low power consumption makes it suitable for battery-powered or low-voltage automotive applications.

Features

The TLC277CD features include:

• Trimmed offset voltage of 500uV max at 25°C, VDD = 5V
• Input offset voltage drift of typically 0.1uV/month, including the first 30 days
• Wide range of supply voltages over specified temperature ranges (3V-16V at 0°C-70°C, 4V-16V at -40°C-85°C, 4V-16V at -55°C-125°C)
• Single-supply operation
• Common-mode input voltage range extends below the negative rail (C-Suffix and I-Suffix types)
• Low noise of typically 25nV/Hz at f=1kHz
• Output voltage range includes negative rail
• High input impedance of typically 10^12 Ohms
• ESD-protection circuitry
• Small-outline package option available in tape and reel
• Designed-in latch-up immunity

These features make the TLC277CD suitable for applications such as precision amplification, sensor signal conditioning, instrumentation and control systems, data acquisition, and audio signal processing.

Package

The package type of TLC277CD is SOIC-8 (Small Outline Integrated Circuit - 8 pins).

Pinout

The TLC277CD is an op-amp packaged in a SOIC-8 package, which means it has 8 pins. Here's a concise breakdown of each pin: 1. VCC: Positive supply voltage 2. VEE: Negative supply voltage (or ground) 3. OUT: Output pin 4. IN+: Non-inverting input pin 5. IN–: Inverting input pin 6. COMP: Compensation pin (for frequency compensation) 7. NC: No connection (not connected to anything) 8. GND: Ground The TLC277CD is a dual op-amp, meaning it has two identical amplifier circuits on the same chip.

Manufacturer

The manufacturer of the TLC277CD is Texas Instruments (TI). Texas Instruments is a leading semiconductor company that designs, manufactures, and tests semiconductors and related products. The company was founded in 1930 and is headquartered in Dallas, Texas, USA. TI is known for its wide range of products, including analog and embedded processing chips, as well as its expertise in areas such as automotive, industrial, and consumer electronics.

Applications

The TLC277CD is commonly used in precision amplification, sensor signal conditioning, instrumentation and control systems, data acquisition, and audio signal processing. It's also suitable for battery-powered or low-voltage automotive applications due to its low power consumption and supply voltage range.
