ATE Figure 3. 8-Lead LFCSP VD (CP-8-13) Medical GENERAL DESCRIPTION The ADA4627-1/ADA4637-1 are wide bandwidth precision The ADA4627-1/ADA4637-1 are specified for both the amplifiers featuring low noise, very low offset, drift, and bias industrial temperature range of 25C to +85C and the current. The devices operate from 5 V to 15 V dual supply. extended industrial temperature range of 40C to +125C. The ADA4627-1/ADA4637-1 are available in tiny 8-lead LFCSP and The ADA4627-1/ADA4637-1 provide benefits previously found 8-lead SOIC packages. in few amplifiers. These amplifiers combine the best specifications of precision dc and high speed ac op amps. The ADA4637-1 is The ADA4627-1/ADA4637-1 are members of a growing series a decompensated version of the ADA4627-1 and is stable at a of high speed, precision op amps offered by Analog Devices, Inc. noise gain of 5 or greater. (see Table 1). With a typical offset voltage of only 70 V, drift of less than 1 V/C, and noise of only 0.86 V p-p (0.1 Hz to 10 Hz), the ADA4627-1/ADA4637-1 are suited for applications where error sources cannot be tolerated.
