It delivers a gain-bandwidth product of 279 MHz and a slew rate of 9V/µs, making it suitable for wideband signal conditioning in applications such as ultrasound front-ends, data acquisition systems, and video distribution. The differential output simplifies driving differential-input ADCs or transmitting signals over twisted-pair cables with common-mode noise rejection. The part operates from a 2.9 V to 5.5 V supply and is rated over the -40°C to 125°C industrial temperature range, covering outdoor telecom, factory-floor automation, and automotive cabin environments. ## Key ratings and what they mean for the BOM The 279 MHz gain-bandwidth product and 9V/µs slew rate support signal conditioning up to several tens of MHz with programmable gain. ## Lifecycle and sourcing posture The MAX9939AUB+ carries an active lifecycle status with ROHS3 compliance. No last-time-buy or obsolescence notice is in effect, so it remains suitable for new designs and production BOMs. For current pricing and availability, the part is sourced and quoted to order through independent distribution; confirmed pricing and lead time are provided at quote time against an RFQ.","metaTitle":"MAX9939AUB+ Programmable Gain Amplifier, 279 MHz, 9V/µs","metaDescription":"MAX9939AUB+ is an active dual-channel programmable-gain op-amp from Analog Devices.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tube","Slew Rate":"9V/µs","Output Type":"Differential","Mounting Type":"Surface Mount","Amplifier Type":"Programmable Gain","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"3.4mA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"1 pA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"279 MHz","Voltage - Input Offset":"1.5 mV","Supplier Device Package":"10-uMAX/uSOP","Current - Output / Channel":"70 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.9 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.92000","currency":"USD"},{"qty":10,"price":"$3.52200","currency":"USD"},{"qty":25,"price":"$3.33000","currency":"USD"},{"qty":100,"price":"$2.88600","currency":"USD"},{"qty":250,"price":"$2.73800","currency":"USD"},{"qty":500,"price":"$2.45680","currency":"USD"},{"qty":1000,"price":"$2.22000","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX9939.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX9939AUB+ require external resistors to set gain?","answer":"No, the MAX9939AUB+ is a programmable-gain amplifier; gain is set via an internal register or pin strapping, eliminating external resistor networks."},{"question":"What is the pinout of MAX9939AUB+?","answer":"The MAX9939AUB+ is supplied in a 10-pin uMAX/uSOP package (10-TFSOP, 10-MSOP).
