Product details

300 V/µs slew rate, 70 MHz bandwidth — what this amplifier is built for

Its 300 V/µs slew rate and 70 MHz -3 dB bandwidth put it in the class of parts that handle fast pulse signals and video-rate waveforms, not just slow sensor conditioning. The 35 mA supply current per channel tells you it's biased for speed, not micropower — this is the part you reach for when a 20 mA output per channel needs to slew a capacitive load or drive a coaxial cable without rounding off the edges.

That means a standard ±5 V analog rail works, but a single 5 V supply does not — the part lacks a true rail-to-rail input or output stage that would let it swing to ground on a single supply. If your board only has a single 5 V rail, this part won't fit without generating a negative rail. The 8-SOIC footprint is common, so layout reuse across a dual-supply analog section is straightforward.

Package and handling: 8-SOIC in tube

If your pick-and-place line expects reels, factor in a tube-to-reel transfer or order the tape-and-reel variant if one exists. The 8-SOIC body is 3.90 mm wide — standard SOIC-8 footprint, no surprises for the PCB layout engineer.

Frequently asked questions

Can MAX457CSA+ operate from a single 5 V supply?

No. A single 5 V rail will not work because the input and output stages are not rail-to-rail. You need a bipolar supply — typically ±5 V — to keep the amplifier in its linear region.

What is the difference between MAX457CSA+ and MAX457CSA?

The MAX457CSA+ is the ROHS3-compliant version of the MAX457CSA. Electrically they are identical — same slew rate, bandwidth, supply range, and package. The '+' suffix indicates lead-free / RoHS compliance. If your assembly process requires ROHS3, the MAX457CSA+ is the correct order code.

Can MAX457CSA+ be used in video applications?

Yes. With a 300 V/µs slew rate and 70 MHz -3 dB bandwidth, the MAX457CSA+ is fast enough for standard-definition video (NTSC/PAL) and many high-speed analog signal chains. The 20 mA output per channel can drive a 75 Ω load with reasonable signal integrity, though for broadcast-grade video you may want a dedicated video amplifier with differential gain/phase specs.
