Introduction
The ADA4638-1 is a high voltage, high precision zero-drift amplifier with rail-to-rail output swing, guaranteed to operate from a 4.5 V to 30 V single supply or ±2.25 V to ±15 V dual supply. Power consumption is less than 0.95 mA from a ±5 V supply.
The ADA4638-1 features a 4 μV offset voltage, less than 0.05 μV/°C offset drift, no 1/f noise, and an input voltage noise of only 1.2 μV p-p (0.1 Hz to 10 Hz), making it suitable for high precision applications where large error sources cannot be tolerated. The near-zero drift of this device over a wide operating temperature range makes it highly beneficial for pressure sensor, medical equipment, and strain gauge amplifier applications. Many applications can take advantage of the rail-to-rail output swing provided by the ADA4638-1 to maximize SNR.
The ADA4638-1 is rated over the −40°C to +125°C extended industrial temperature range and is available in 8-lead LFCSP (3 mm × 3 mm) and SOIC packages.
