The LTC6430-15 is a differential gain block amplifier designed to drive high resolution, high speed ADCs with excellent linearity beyond 1000MHz and with low associated output noise. The LTC6430-15 operates from a single 5V power supply and consumes only 800mW. In its differential configuration, the LTC6430-15 can directly drive the differential inputs of an ADC. Using 1:2 baluns, the device makes an excellent 50 Ohms wideband balanced amplifier. While using 1:1.33 baluns, the device makes a high fidelity 50MHz to 1000MHz 75 ohm CATV amplifier. The LTC6430-15 is designed for ease of use, requiring a minimum of support components. The device is internally matched to 100 ohm differential source/load impedance. Onchip bias and temperature compensation ensure consistent performance over environmental changes. The LTC6430-15 uses a high performance SiGe BiCMOS process for excellent repeatability compared with similar GaAs amplifiers. All A-grade LTC6430-15 devices are tested and guaranteed for OIP3 at 240MHz. The LTC6430-15 is housed in a 4mm x 4mm, 24-lead, QFN package with an exposed pad for thermal management and low inductance. For a single-ended 50 Ohm IF gain block with similar performance, see the related LTC6431-15.
