Differential amplifier for high-speed signal chains
The Texas Instruments THS4131IDGN is a single-channel differential amplifier in an 8-HVSSOP package with an exposed thermal pad. Its 150 MHz -3dB bandwidth and 52 V/µs slew rate suit driving differential-input ADCs and balanced line drivers.
150 MHz bandwidth and 52 V/µs slew rate — what they mean on the bench
The 150 MHz -3dB bandwidth sets the small-signal frequency range for the differential path. The 52 V/µs slew rate handles large-signal steps; output current limit is 85 mA per channel.
Differential output — what it saves you
The output is differential, not single-ended. Input bias current is 2 µA typical; input offset voltage is 200 µV.
Package and thermal handling
The 8-HVSSOP package has an exposed pad on the bottom. That pad must be soldered to a PCB copper plane for thermal and ground return.
Lifecycle and sourcing
The THS4131IDGN carries an Active product status and ROHS3 compliance. No last-time-buy notice or obsolescence is on record.
