LT5514 - Ultralow Distortion IF Amplifier/ADC Driver With Digitally Controlled Gain

The LT5514 is a Programmable Gain Amplifier (PGA) with bandwidth extending from low frequency (LF) to 850MHz. It consists of a digitally controlled variable Attenuator followed by a high linearity Amplifier The Amplifier is configured with two identical transconductance Amplifiers hard wired in parallel with individual dedicated enable pins. When both Amplifiers are enabled (Standard mode), the LT5514 offers an OIP3 of +47dBm (at 100MHz). Power dissipation CAN be reduced when a single Amplifier is enabled (Low Power mode). Four parallel digital inputs control the gain over a 22.5dB range with 1.5dB step resolution. An on-chip power supply Regulator Filter helps isolate the Amplifier signal path from external noise sources.
The LT5514s open-loop architecture offers stable operation for any practical load conditions, including peaking-free AC response when driving capacitive loads, and excellent reverse isolation.
The LT5514 may be operated Broadband where the output differential RC time constant sets the bandwidth, or it may be used as a narrowband driver with the appropriate output Filter
