Supply Voltage . 6. The low input offset voltage of 50 µV (200 µV max) ensures ±7.5 V Input Voltage (Pin 1 or Pin 20 to COM) . –3 V to +300 mV good accuracy for low level dc inputs. Attenuator Input Voltage (Pin 5 to Pin 3/4) . ± 4 V 7. Thermal recovery “tails,” which can obscure the response Storage Temperature Range D, E . –65°C to +150°C when a small signal immediately follows a high level input, Storage Temperature Range N, P . –65°C to +125°C have been minimized by special attention to design details. Ambient Temperature Range, Rated Performance 8. The noise spectral density of 2 nV/√Hz results in a noise floor of Industrial, AD640B . –40°C to +85°C ~23 µV rms (–80 dBm) at a bandwidth of 100 MHz. The dy- Military, AD640T . –55°C to +125°C namic range using cascaded AD640s can be extended to 95 dB Commercial, AD640J . 0°C to +70°C by the inclusion of a simple filter between the two devices. Lead Temperature Range (Soldering 60 sec) . +300°C *Stresses above those listed under Absolute Maximum Ratings may cause perma- nent damage to the device. This is a stress rating only; functional operation of the
