Low Distortion IF

Amplifier/ADC Driver with

Digitally Controlled Gain

FEATURES

DESCRIPTIO

TheLT^®5524isaprogrammablegainamplifier(PGA)with

bandwidth extending from low frequency (LF) to 540MHz.

It consists of a digitally controlled variable attenuator,

followed by a high linearity amplifier. 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.

■

Output IP3 at 100MHz: 40dBm

■

Maximum Output Power: 16dBm

■

Bandwidth: LF to 540MHz

■

Propagation Delay: 0.8ns

■

Maximum Gain: 27dB

■

Gain Control Range: 22.5dB

■

Gain Control Step: 1.5dB

■

Gain Control Settling Time: 500ns

■

Noise Figure: 8.6dB at 100MHz (Max Gain)

The LT5524’s open-loop architecture offers stable opera-

tion for any practical load conditions, including peaking-

free AC response when driving capacitive loads, and

excellent reverse isolation.

■

Output Noise Floor: –138dBm/Hz (Max Gain)

■

Reverse Isolation: –92dB

■

Single Supply: 4.75V to 5.25V

■

Shutdown Mode

■

The LT5524 may be operated broadband, where the out-

put differential RC time constant sets the bandwidth, or it

may be used as a narrowband driver with the appropriate

output filter.

Enable/Disable Time: 1µs
