Product details

Active production — no obsolescence risk on this BOM line

The LT1991IMS#TRPBF: No minimum order threshold beyond the reel increment.

560 kHz GBP, 110 kHz -3dB — precision signal conditioning

Programmable-gain amplifier with 560 kHz gain-bandwidth product and 110 kHz -3 dB bandwidth. Input offset voltage is 25 µV typical with 2.5 nA input bias current — the offset error at the output after gain is small enough to skip auto-zero calibration in many 12-bit systems. Supply current is 130 µA, output can source or sink 21 mA per channel.

A single-circuit PGA in a 10-MSOP package — one channel per chip, useful when each channel needs independent gain programming or isolation from adjacent paths. The 10-MSOP footprint (3.00 mm width) fits tight multi-layer boards; the 0.50 mm lead pitch demands a controlled soldering profile but is standard for this package class.
