Linear Technology LTC2246HLX#PBF High-Speed ADC

The LTC2246HLX#PBF is a high-performance, 14-bit, 25Msps (Mega samples per second) analog-to-digital converter (ADC) from Linear Technology, a leader in the design and manufacture of high-performance analog integrated circuits. This ADC is designed to offer excellent dynamic performance, low noise and low power consumption, making it an ideal choice for a wide range of applications, including communications systems, medical imaging, and industrial instrumentation.

Featuring a differential sample-and-hold input stage, the LTC2246HLX#PBF allows for a wide input bandwidth while maintaining the excellent SNR (Signal-to-Noise Ratio) and SFDR (Spurious-Free Dynamic Range) that are critical in high-speed signal processing. This makes the LTC2246HLX#PBF suitable for demanding applications such as IF sampling in wireless and wired broadband communications.

The LTC2246HLX#PBF operates from a single 3.3V supply and includes an internal bypass capacitor to simplify the power supply design. The device also offers an optional internal dithering feature, which can be used to improve the ADC's SFDR performance with input signals that are near the Nyquist frequency.

With its small footprint, the LTC2246HLX#PBF is available in a 32-lead 5mm x 5mm QFN package, which is ideal for space-constrained applications. The device also supports a flexible output interface that can be configured for either CMOS or LVDS (Low-Voltage Differential Signaling) outputs, allowing for easy integration with a variety of digital signal processors and FPGAs.

Linear Technology's LTC2246HLX#PBF ADC also includes features such as a shutdown mode to reduce power consumption when the device is not in use, and a sleep mode for quick recovery to full operation. To ensure reliable performance across different environmental conditions, the device is specified over the industrial temperature range of -40°C to 85°C.

Overall, the LTC2246HLX#PBF from Linear Technology is a versatile and reliable ADC solution that delivers high-speed performance with exceptional quality, making it a top choice for engineers and designers working on advanced digital signal processing systems.
