Current mirror with ±0.5 dB gain accuracy
The DS3923T+T from Analog Devices is an active-production current mirror in a 24-TQFN (3.5x3.5) package. Its ±0.5 dB gain accuracy means the mirrored output current tracks the reference within a tight 0.5 dB window across the input range — critical for biasing chains where current-ratio precision sets the operating point of downstream gain stages or laser drivers.
Package, temperature grade, and compliance
Housed in a 24-WFQFN exposed-pad package (supplier device package 24-TQFN 3.5x3.5 mm), the DS3923T+T is rated for the -40°C to +95°C industrial temperature range.
