LTC6912AIGN-1 Dual Programmable Gain Amplifier

The LTC6912AIGN-1 is a high-performance, dual programmable gain amplifier (PGA) designed by Linear Technology, now part of Analog Devices, to cater to a wide range of applications requiring precise gain control and high signal integrity. This versatile component is ideal for use in automatic test equipment, data acquisition systems, medical instrumentation, and industrial process controls, among others.

Constructed with advanced silicon technology, the LTC6912AIGN-1 offers users the flexibility to digitally select the desired gain from 0dB up to 50dB in 6dB steps through a 3-wire SPI interface. This feature allows for easy integration into digital systems, providing dynamic control over the gain settings to match the requirements of the application.

The device operates with a single 2.7V to 5.5V supply or a dual ±2.7V to ±5.5V supply, making it adaptable to various power environments. It also boasts a wide bandwidth and low noise performance, ensuring that signals are amplified accurately and with minimal distortion. The LTC6912AIGN-1 has a slew rate of 2.8V/µs, which is suitable for moderate speed applications.

Enclosed in a 16-lead SSOP package, the LTC6912AIGN-1 is designed for compactness and reliability. Its industrial temperature range from -40°C to 85°C guarantees stable operation across diverse environmental conditions. Additionally, the part features a shutdown mode that reduces the current consumption to 4µA, providing an effective power-saving option for battery-powered devices.
