TLC7226CN

TLC7226CN Description

The TLC7226CN from Texas Instruments is an 8-bit, quad-channel digital-to-analog converter (DAC) designed for precision voltage output applications. Housed in a 20-pin DIP package, this through-hole-mount device operates over a 0°C to 70°C temperature range, making it suitable for industrial and commercial environments. It features a parallel data interface for straightforward integration with microcontrollers and logic circuits. With an external reference voltage input, the TLC7226CN offers flexibility in setting the output range, while its ±1 LSB integral and differential nonlinearity (INL/DNL) ensures high accuracy. The 20µs settling time enables rapid response in dynamic systems, and its ROHS3 compliance meets modern environmental standards.

TLC7226CN Features

• Quad 8-bit DACs: Four independent DAC channels in a single package, reducing board space and cost.
• Parallel Interface: Simplifies communication with microprocessors or digital systems.
• Low INL/DNL Error: ±1 LSB max ensures precise analog output generation.
• External Reference: Supports adjustable full-scale output voltage for versatile design needs.
