The 20-pin DIP package (0.300\" width, 7.62mm pitch) makes it a practical choice for bench prototypes, repair swaps, and low-to-medium volume production where through-hole assembly is preferred over fine-pitch SMD. On-chip features include differential inputs, a mute function, shutdown control, thermal protection, and volume control — reducing external BOM count for basic stereo applications. ## Output power and load matching Rated at 2W x 2 into 4Ω, the TPA6021A4N is sized for driving small speakers in desktop speakers, portable radios, or intercom panels. The 4V to 5.5V supply range aligns with single 5V rails or 3.7V Li-ion battery packs. The separate headphone output lets the same amplifier serve both speaker and headphone listening without an external switch — useful for multi-media or test equipment front panels. ## Temperature grade and environment The through-hole DIP package handles moderate rework cycles and is compatible with socketed prototyping.","metaTitle":"TPA6021A4N Class AB stereo amplifier, 2W x 2 @ 4Ω, 20-DIP","metaDescription":"Texas Instruments TPA6021A4N Class AB audio amplifier, 2W per channel into 4Ω stereo with headphone output, 20-pin DIP, -40°C to 85°C, RoHS3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Class AB","Package":"Tube","Features":"Differential Inputs, Mute, Shutdown, Thermal Protection, Volume Control","Output Type":"2-Channel (Stereo) with Stereo Headphones","Mounting Type":"Through Hole","Package / Case":"20-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-PDIP","Max Output Power x Channels @ Load":"2W x 2 @ 4Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.57","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.57000","currency":"USD"},{"qty":10,"price":"$4.10200","currency":"USD"},{"qty":25,"price":"$3.87800","currency":"USD"},{"qty":100,"price":"$3.36090","currency":"USD"},{"qty":250,"price":"$3.18860","currency":"USD"},{"qty":500,"price":"$2.86110","currency":"USD"},{"qty":1000,"price":"$2.43900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/efb5da6d30226f4915712851d9618a03.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TPA6021A4N a direct replacement for TPA6021A2?","answer":"The TPA6021A2 is a related variant in the same family, but pin compatibility depends on the specific package and feature set.
