The AD8634-KGD is a precision, 9.7 MHz bandwidth, dual
amplifier that features rail-to-rail outputs. The AD8634-KGD is
guaranteed to operate from 3 V to 30 V (or from ±1.5 V to
±15 V) and at very high temperatures. The AD8634-KGD is
specified and characterized for −40°C to +210°C and is tested at
+175°C.
The AD8634-KGD is well suited for applications that require …
