RS624XQ

Jiangsu RUNIC Tech · Operational Amplifier · TSSOP-14

RS624XQ from Jiangsu RUNIC Tech, in a TSSOP-14. 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	OUT A	output	Amplifier A output. Rail-to-rail CMOS output, typical short-circuit current 50 mA; swings within ~7 mV of the rails with a 10 kΩ load.
2	-IN A	input	Inverting input of amplifier A. Rail-to-rail common-mode range of -0.1 V to 5.6 V (with Vs=5.5V); input bias current typically 1 pA.
3	+IN A	input	Non-inverting input of amplifier A. Rail-to-rail common-mode range; ultra-low input bias current (~1 pA typical).
4	V+	power_in	Positive supply pin. Operating range 2.5 V to 5.5 V single-supply (±1.25 V to ±2.75 V dual-supply). Bypass with 0.1 uF close to the pin; absolute max V+ to V- is 7.0 V.
5	+IN B	input	Non-inverting input of amplifier B. Rail-to-rail common-mode range; ultra-low input bias current.
6	-IN B	input	Inverting input of amplifier B. Rail-to-rail common-mode range; ultra-low input bias current.
7	OUT B	output	Amplifier B output. Rail-to-rail CMOS output; typical short-circuit current 50 mA.
8	OUT C	output	Amplifier C output. Rail-to-rail CMOS output; typical short-circuit current 50 mA.
9	-IN C	input	Inverting input of amplifier C. Rail-to-rail common-mode range; ultra-low input bias current.
10	+IN C	input	Non-inverting input of amplifier C. Rail-to-rail common-mode range; ultra-low input bias current.
11	V-	power_in	Negative supply / ground pin. Tie to GND for single-supply operation or to the negative rail for dual-supply. Bypass with 0.1 uF close to the pin.
12	+IN D	input	Non-inverting input of amplifier D. Rail-to-rail common-mode range; ultra-low input bias current.
13	-IN D	input	Inverting input of amplifier D. Rail-to-rail common-mode range; ultra-low input bias current.
14	OUT D	output	Amplifier D output. Rail-to-rail CMOS output; typical short-circuit current 50 mA.

CAD (KiCad official)

Symbol: RS624XQ
Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
3D model: TSSOP-14 (KiCad packages3D, STEP)
3D model files: rs624xq-etched.step / rs624xq-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rs624xq.step / rs624xq.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`rs624xq.step`	194 KB	You want the bare part, or you mark your own boards.
`rs624xq-etched.step`	2.1 MB	You want the part with `RS624XQ` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 522 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
