LM334SMX

Texas Instruments · Current Source / Constant Current Source · SOIC-8

LM334SMX from Texas Instruments, in a SOIC-8. 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 V- power_in Negative terminal of the floating current source (current-out side); the datasheet rates V+ to V- forward voltage at 40V max.
2 R passive Set-resistor pin where RSET connects to establish ISET (approx. 67.7 mV/RSET at 25°C); voltage from R to V- is limited to 5V max.
3 V+ power_in Positive terminal of the floating current source; set current ISET flows into this pin, with 40V max forward and 20V max reverse voltage to V-.
4 NC unconnected No internal connection.
5 NC unconnected No internal connection.
6 NC unconnected No internal connection.
7 NC unconnected No internal connection.
8 NC unconnected No internal connection.
