That output power is measured at the device pins — the actual SPL at the speaker depends on the enclosure and driver efficiency, but the amplifier itself won't be the bottleneck for a portable Bluetooth speaker or a docking station channel. At 3.6 V battery mid-point, expect roughly 1.5–2 W per channel into 4 Ω — the 3.2 W headline figure is reached at the 5.0 V supply end of the range. ## I²C volume and SmartGain™ — what the control bus buys you Volume is set via I²C, not a potentiometer or DC voltage — the gain register is 32-step from mute to +24 dB. That eliminates the wiper-noise and tracking-error issues of an analog pot in a portable product. SmartGain™ is an automatic gain control (AGC) that prevents the output from clipping when the input signal exceeds the supply headroom. The attack and release times are programmable over I²C — useful when the source is a Bluetooth stream with unpredictable peak levels. Differential inputs reject common-mode noise from the ground loop between the codec and the amplifier — a real concern when the two ICs sit on opposite sides of a two-layer board. ## Package and thermal reality — 16-DSBGA (2.24 × 2.16 mm) The 16-DSBGA package measures 2.24 × 2.16 mm with a 0.50 mm ball pitch. That pitch is fine for a two-layer board if the fan-out traces are 0.10 mm width — four-layer is safer for production yield. The Class-D output stage runs cool at typical listening levels — efficiency is above 85 % at 1 W output, so the die temperature stays well below 85 °C ambient even without a heatsink. The DSBGA's thermal pad on the bottom side should be connected to a ground plane pour for best thermal transfer. Surface-mount only — no through-hole variant exists. The DSBGA package requires a solder-paste stencil and reflow profile; hand-soldering is not practical. A portable instrument that plays audio prompts outdoors in winter or a dashcam that sits in a parked car in summer stays within the rated junction temperature.","metaTitle":"TPA2026D2YZHT Class-D Stereo Amp, 3.2W×2 @ 4Ω, DSBGA","metaDescription":"Texas Instruments TPA2026D2YZHT Class-D stereo amplifier, 3.2W per channel into 4Ω, I²C volume control, 2.5-5.5V supply, -40 to 85°C, active production, ROHS3","metaKeywords":null},"attributes":{"series":"SmartGain™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Class D","Series":"SmartGain™","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Differential Inputs, I²C, Short-Circuit and Thermal Protection, Shutdown, Volume Control","Output Type":"2-Channel (Stereo)","Mounting Type":"Surface Mount","Package / Case":"16-UFBGA, DSBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"2.5V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"16-DSBGA (2.24x2.16)","Max Output Power x Channels @ Load":"3.2W x 2 @ 4Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8","priceTiers":[{"qty":1,"price":"$2.80000","currency":"USD"},{"qty":10,"price":"$2.51400","currency":"USD"},{"qty":25,"price":"$2.37160","currency":"USD"},{"qty":100,"price":"$2.02070","currency":"USD"},{"qty":250,"price":"$1.89740","currency":"USD"},{"qty":500,"price":"$1.66022","currency":"USD"},{"qty":1250,"price":"$1.37562","currency":"USD"},{"qty":2500,"price":"$1.34250","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a5b2303172622fc4bf2681a7bf829deb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPA2026D2YZHT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TPA2026D2YZHT and get a price?","answer":"The TPA2026D2YZHT is sourced through independent distribution."},{"question":"What is the closest pin-compatible alternative in the SmartGain family?","answer":"The TPA2026D2 is a single part number; parametric equivalents in the same family may differ in package or I²C address."},{"question":"What compliance documentation does Texas Instruments provide?","answer":"The part is ROHS3 Compliant per the lifecycle record.
