Dual differential amplifier with 135 MHz GBW
The THS4552IPWT is a dual-channel fully differential amplifier with a gain-bandwidth product of 135 MHz and a 220 V/µs slew rate, suited for driving high-speed ADCs or differential signal chains in industrial and test equipment. Rail-to-rail differential output and a supply span from 2.7 V to 5.4 V let it interface with 3.3 V and 5 V converters without extra level shifting.
Package and rework considerations
Housed in a 16-TSSOP (4.40 mm wide) — a fine-pitch but hand-solderable package if you have a decent iron and steady hands. Pin 1 is clearly marked on the top; orientation is unambiguous under a loupe. Surface-mount only; the 0.65 mm pitch means a standard hot-air rework station can lift it cleanly if you preheat the board to 100°C first. No hidden thermal pad underneath — the part lifts without pulling pads.
Precision and drive for signal-chain use
Input offset voltage is 50 µV typical with 1 µA input bias current — tight enough for 16-bit ADC drive without a separate trim circuit. Each channel can source or sink 65 mA, enough to drive a 50-ohm terminated line or a moderate capacitive load. Total supply draw is 1.37 mA per channel (2.74 mA for both), keeping the thermal rise low in the TSSOP package even at elevated ambient temperatures.
Lifecycle and compliance
Rated for -40°C to 125°C operation, covering industrial and automotive under-hood temperature ranges. No AEC-Q grade is stated in the available documentation.
