The differential output pairs naturally with high-speed ADCs that expect a differential input, saving you an external balun or single-ended-to-differential stage. The 40 MHz -3 dB bandwidth covers the fundamental and several harmonics of a 5–10 MHz ultrasound transducer array, which is the classic use case. The 300 V/µs slew rate means the amplifier can swing a large output signal (several volts peak-to-peak) without slewing into distortion — critical when the gain is turned up and the input pulse is fast. Together these specs tell you the part is designed for large-signal dynamic range, not just small-signal AC gain. ## Dual channel, differential output — board layout considerations Two channels in a single 48-TQFP (7x7 mm) save board space compared to two single-channel VGAs. The differential output on each channel means you route a pair of traces per channel to the ADC — keep them matched in length and impedance. Input bias current is 1 nA typical, which is low enough that you do not need a guard ring around the inputs for most layouts, but the 40 mA output per channel can drive a capacitive load like an ADC input directly if you watch the phase margin. Plan for a clean 5 V rail; the 40 MHz bandwidth will couple supply noise into the output if the rail is dirty. Surface-mount only, in a 48-TQFP with a 7x7 mm body — fine for reflow, but the fine pitch (0.5 mm typical for TQFP-48) means a good solder paste stencil and alignment.","metaTitle":"VCA2612Y-1/2K Variable Gain Amplifier, 40 MHz Bandwidth","metaDescription":"VCA2612Y-1/2K variable gain amplifier from Texas Instruments. 40 MHz -3 dB bandwidth, 300 V/µs slew rate, differential output, dual channel, 48-TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Bulk","Slew Rate":"300V/µs","Output Type":"Differential","Mounting Type":"Surface Mount","-3db Bandwidth":"40 MHz","Amplifier Type":"Variable Gain","Package / Case":"48-TQFP","lifecycle_stage":"eol_hot","Number of Circuits":"2","Current - Input Bias":"1 nA","Operating Temperature":"-40°C ~ 85°C","Gain Bandwidth Product":"80 MHz","Supplier Device Package":"48-TQFP (7x7)","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"5.25 V","Voltage - Supply Span (Min)":"4.75 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.32","stockQuantity":0,"priceTiers":[{"qty":17,"price":"$18.32000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6118ee34c0485687e925eb9ccfc66bf7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the -3 dB bandwidth of VCA2612Y-1/2K?","answer":"The -3 dB bandwidth is 40 MHz.
