What this dual CMOS op-amp brings to the bench
The TLV2442AIPWG4: Its rail-to-rail output stage lets you swing close to the supply rails, which is useful in single-supply designs running from 2.7 V up to 10 V. Each channel draws 750 µA supply current, keeping the thermal budget manageable in a tight 8-TSSOP layout.
Package and footprint reality
No exposed thermal pad here; the 8-TSSOP relies on the leads for heat sinking, so keep the copper pour under the part generous if you're pushing the 50 mA output per channel continuously.
Second-source and replacement landscape
There is no direct pin-for-pin second source listed for the TLV2442AIPWG4. The closest functional peer in the TI portfolio is the TLV9351IDCKR — a single-channel CMOS op-amp with 3.5 MHz GBW and 20 V/µs slew rate, but it's a single in a different package (SC-70) and runs on a 4.5 V supply. The TLV9362IDDFR is a dual-channel part with 10.6 MHz GBW and 25 V/µs slew, again on 4.5 V, and in a different package (SOT-23). Neither is a drop-in replacement; you'd need a board spin. For a repair bench looking to bring a dead board back, the scorch mark tells you the original part — and if the TLV2442AIPWG4 is the one that failed, sourcing the exact original is the cleanest path.
Lifecycle and sourcing posture
No last-time-buy risk, no scramble for obsolete-stock brokers — just a straightforward active part that's been in the TI catalog for years.
