ADI AD8276ARMZ-R7

The AD8276 is a general-purpose unity-gain difference amplifier intended for precision signal conditioning in power critical applications that require both high performance and low power. The AD8276 provides exceptional common-mode rejection ratio (86 dB) and high bandwidth while amplifying signals well beyond the supply rails. The on-chip resistors are laser-trimmed for excellent gain accuracy and high commonmode rejection ratio. They also have outstanding gain temperature coefficient. The amplifier’s common-mode range extends to almost double the supply voltage, making it ideal for single-supply applications that require a high common-mode voltage range. The AD8276 is unity-gain stable. Intended as a difference amplifier, it can also be connected in a high precision, singleended configuration with G=-1,+1,+2, or +%. The AD8276 operates on single supplies (2.5 V to 36 V) or dual supplies (±2 V to ±18 V). The maximum quiescent supply current is 220 μA, which makes it ideal for battery operated and portable systems. The AD8276 is available in the space-saving 8-lead MSOP and SOIC packages. It is specified for performance over the industrial temperature range of -40°C to +85°C and is fully RoHS compliant.
