OPA2228PA FAQs

1.Q: Are there related parts to the Texas Instruments OP AMP (DIP-8)?

A: Similar parts include TI’s OPA2134 (higher performance) or LM358 (lower cost), but this model is obsolete per the datasheet.

2.Q: What is the thermal resistance of the Texas Instruments OP AMP (DIP-8) package?

A: Not specified in the datasheet, but the through-hole DIP-8 package typically has θJA ~ 100°C/W (estimated for standard PDIP).

3.Q: Does the Texas Instruments OP AMP (DIP-8) meet automotive or industrial certifications?

A: No. It is not automotive-grade (PPAP/automotive = "No") and has no industry certifications listed (MSL = "-").

4.Q: What is the recommended operating condition for the Texas Instruments OP AMP (DIP-8)?

A: Recommended: Dual supply ±2.5V to ±15V or single supply 4.5V to 36V, -40°C to 85°C ambient temperature.

5.Q: What are the absolute maximum ratings for the Texas Instruments OP AMP (DIP-8)?

A: Absolute max ratings: ±18V dual supply, 36V single supply, 85°C max operating temperature. Exceeding these may damage the device.

6.Q: What are the typical applications for the Texas Instruments OP AMP (DIP-8)?

A: Suitable for precision signal conditioning, active filters, data acquisition systems, and instrumentation due to its low offset voltage (0.2mV max) and high CMRR (120dB min).

7.Q: What is the pinout configuration of the Texas Instruments OP AMP (DIP-8)?

A: The 8-pin DIP package follows standard dual-op-amp pinout: Pin 1 (Output A), Pin 2 (Inverting Input A), Pin 3 (Non-Inverting Input A), Pin 4 (V-), Pin 5 (Non-Inverting Input B), Pin 6 (Inverting Input B), Pin 7 (Output B), Pin 8 (V+).
