汽车类,300MHz,全差分,连续可变增益放大器
The THS7530-Q1 device is fabricated using Texas Instruments" state-of-the-art BiCom III SiGe complementary bipolar process. The THS7530-Q1 device is a DC-coupled, wide bandwidth amplifier with voltage-controlled gain. The amplifier has high-impedance differential inputs and low-impedance differential outputs with high-bandwidth gain control, output common-mode control, and output voltage clamping.
Signal-channel performance is exceptional with 300-MHz bandwidth, and third harmonic distortion of –61 dBc at 32 MHz with 1-VPP output into 400 Ω.
Gain control is linear in dB with 0 V to 0.9 V varying the gain from 11.6 dB to 46.5 dB with 38.8-dB/V gain slope.
Output voltage limiting is provided to limit the output voltage swing and to prevent saturating following stages.
The device is characterized for operation over the automotive temperature range, –40°C to +125°C.
