Each of the four channels delivers rail-to-rail output swing, 32 mA output current, and a 10V/µs slew rate with 8 MHz -3dB bandwidth — enough to settle the gamma reference lines within the horizontal blanking interval of most LCD resolutions up to full HD. Supply current sits at 1.1 mA per amplifier, keeping the total thermal budget low in the tight 14-TSSOP package that fits alongside the timing controller on a slim panel driver PCB. ## Supply range and rail headroom The single-supply range spans 3.5 V to 12 V, or ±1.75 V to ±6 V in split-supply mode. For a typical 5 V or 3.3 V LCD controller supply, the 3.5 V minimum means a 3.3 V rail is below the guaranteed operating floor — plan for a 5 V rail or a boost converter if running from 3.3 V logic. The rail-to-rail output stage maintains swing within millivolts of each supply rail, which is critical for preserving the full gamma range when the reference voltages sit near the supply limits. ## Package and footprint for panel assembly Housed in a 14-lead TSSOP (4.40 mm width), the BUF04701AIPWRG4 uses the standard JEDEC MO-153 footprint shared with many TI gamma buffers and general-purpose quad op-amps. The surface-mount package suits automated pick-and-place for high-volume panel module assembly. ## Lifecycle and compliance status The ROHS3 rating covers the full substance restriction set including the four phthalates, so it passes EU regulatory screening without exemption paperwork.","metaTitle":"BUF04701AIPWRG4 Quad Rail-to-Rail Buffer, 10V/µs Slew Rate","metaDescription":"Texas Instruments BUF04701AIPWRG4 quad CMOS rail-to-rail buffer amp for TFT-LCD gamma correction. 10V/µs slew rate, 8 MHz bandwidth, 1.1 mA supply, 32 mA","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Bulk","Slew Rate":"10V/µs","Output Type":"Rail-to-Rail","Applications":"TFT-LCD Panels: Gamma Buffer","Mounting Type":"Surface Mount","-3db Bandwidth":"8 MHz","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1.1 mA","Number of Circuits":"4","Supplier Device Package":"14-TSSOP","Current - Output / Channel":"32 mA","Voltage - Supply, Single/Dual (±)":"3.5V ~ 12V, ±1.75V ~ 6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0","stockQuantity":0,"priceTiers":[{"qty":301,"price":"$1.00000","currency":"USD"}]},"links":{"datasheetUrl":"https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=https%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Fbuf04701","sourceUrl":null},"ai":{"faq":[{"question":"How many channels does BUF04701AIPWRG4 have?","answer":"The BUF04701AIPWRG4 contains four independent buffer amplifier circuits in a single package."},{"question":"What is the output current capability of BUF04701AIPWRG4?","answer":"Each channel can source or sink up to 32 mA of output current, rail-to-rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BUF04701AIPWRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BUF04701AIPWRG4 when reusing this data.
