A user adjustable CBYP can significantly reduce low frequency 1/f noise (8 nV/rtHz at 100 Hz) for precision analog front-end measurement systems.
With line and load transient responses of 0.01%/V and 0.4%/A with a 10-µF ceramic output capacitor, the ADM7150/1 also feature high power-supply rejection ratio performance of greater than 90 dB from 1 kHz to 100 kHz, and greater than 60 dB at 1 MHz.
Minimising the size of discrete filtering components normally needed, this effectively filters DC-DC switching regulator ripple, saving space.
The ADM7150 (with a fixed Vout) is available now in 3-mm x 3-mm, 8-lead LFCSP and SOIC packages, priced at $3.64 (USD) each in 1,000 unit quantities. The ADM7151 is offered in the same package at the same price but features an adjustable Vout.
