OPA2141AIDGKR

Texas Instruments · FET Input Amplifiers · MSOP-8

OPA2141AIDGKR from Texas Instruments, in a MSOP-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	OUT A	output	Channel A output, rail-to-rail swing to within (V-)+0.2V and (V+)-0.2V with RL = 10kΩ, with continuous short-circuit protection (source +36mA, sink -30mA).
2	-IN A	input	Channel A inverting input, diode-clamped to the supply rails with signals beyond 0.5V outside the rails to be current limited to 10mA or less.
3	+IN A	input	Channel A non-inverting input, diode-clamped to the supply rails with input range including V- and signals beyond 0.5V outside the rails to be current limited to 10mA or less.
4	V-	power_in	Negative supply (ground in single-supply use), with specified total supply range of 4.5V to 36V (±2.25V to ±18V).
5	+IN B	input	Channel B non-inverting input, diode-clamped to the supply rails with input range including V- and signals beyond 0.5V outside the rails to be current limited to 10mA or less.
6	-IN B	input	Channel B inverting input, diode-clamped to the supply rails with signals beyond 0.5V outside the rails to be current limited to 10mA or less.
7	OUT B	output	Channel B output, rail-to-rail swing to within (V-)+0.2V and (V+)-0.2V with RL = 10kΩ, with continuous short-circuit protection (source +36mA, sink -30mA).
8	V+	power_in	Positive supply, with specified total supply range of 4.5V to 36V (±2.25V to ±18V) and absolute maximum supply voltage of ±20V.

CAD (KiCad official)

Symbol: OPA2141AIDGKR
Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
3D model: MSOP-8 (KiCad packages3D, STEP)
3D model files: opa2141aidgkr-etched.step / opa2141aidgkr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa2141aidgkr.step / opa2141aidgkr.glb are the bare package body.
