3 Description
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-V_PP 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.
