UA733CNSR

Texas Instruments · Operational Amplifier · SOIC-14-208mil

UA733CNSR from Texas Instruments, in a SOIC-14-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN+ input Non-inverting differential input of the video amplifier, with a differential input voltage limit of ±5 V and a common-mode input voltage limit of ±6 V.
2 NC unconnected No internal connection.
3 GAIN ADJ 2A passive Gain-adjust pin 2A; connecting it to pin 2B (with 1A/1B open) selects the nominal gain of 100 V/V (gain option 2).
4 GAIN ADJ 1A passive Gain-adjust pin 1A; connecting it to pin 1B (with 2A/2B open) selects the nominal gain of 400 V/V (gain option 1), or a resistor between 1A and 1B adjusts gain from 10 V/V to 400 V/V.
5 VCC− power_in Negative supply voltage, absolute maximum -8 V with respect to the midpoint between VCC+ and VCC−.
6 NC unconnected No internal connection.
7 OUT+ output Non-inverting emitter-follower differential output, able to drive capacitive loads, with output current limited to 10 mA maximum.
8 OUT− output Inverting emitter-follower differential output, able to drive capacitive loads, with output current limited to 10 mA maximum.
9 NC unconnected No internal connection.
10 VCC+ power_in Positive supply voltage, absolute maximum 8 V with respect to the midpoint between VCC+ and VCC−.
11 GAIN ADJ 1B passive Gain-adjust pin 1B; connect to pin 1A to select the nominal gain of 400 V/V (gain option 1), or connect an external resistor between 1A and 1B to adjust gain from 10 V/V to 400 V/V.
12 GAIN ADJ 2B passive Gain-adjust pin 2B; connecting it to pin 2A (with 1A/1B open) selects the nominal gain of 100 V/V (gain option 2).
13 NC unconnected No internal connection.
14 IN− input Inverting differential input of the video amplifier, with a differential input voltage limit of ±5 V and a common-mode input voltage limit of ±6 V.
