tp8542arz.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 8 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

TP8542ARZ

TECH PUBLIC · Operational Amplifier · SOP-8

TP8542ARZ from TECH PUBLIC, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTA output Amplifier A output. Rail-to-rail CMOS output stage, VOL-VSS/VDD-VOH within 6 mV of the rails at RL=100 kOhm; short-circuit current typ. +/-20 mA.
2 INA- input Amplifier A inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input).
3 INA+ input Amplifier A non-inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input).
4 VSS power_in Negative supply / ground. Typically tied to 0 V in single-supply operation. Absolute maximum VDD-to-VSS = 7 V; input voltage range VSS-0.5 V to VDD+0.5 V.
5 INB+ input Amplifier B non-inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input).
6 INB- input Amplifier B inverting input. High-impedance CMOS input, typ. 10 pA input bias current; common-mode range -0.1 V to VDD+0.1 V (rail-to-rail input).
7 OUTB output Amplifier B output. Rail-to-rail CMOS output stage, VOL-VSS/VDD-VOH within 6 mV of the rails at RL=100 kOhm; short-circuit current typ. +/-20 mA.
8 VDD power_in Positive supply, +2.5 V to +5.5 V single-supply operation (absolute max 7 V VDD-to-VSS). Typical quiescent current 40 uA per amplifier (80 uA total). Bypass with a local ceramic decoupling capacitor.
