The AD8513ARUZ is a quad-channel precision JFET operational amplifier manufactured by Analog Devices. Housed in a 14-lead TSSOP package, it delivers very low noise (8 nV\/\u221aHz at 1 kHz), ultra-low input bias current (25 pA typical), and low offset voltage (400 \u03bcV max for B grade). With a gain bandwidth product of 8 MHz and a slew rate of 20 V\/\u03bcs, it is designed for high-impedance sensor amplification, precision current measurement, and high-performance filtering applications across the -40\u00b0C to +125\u00b0C industrial temperature range.<\/p>\n

It combines low offset voltage (400 \u03bcV max for B grade), ultra-low input bias current (25 pA typical), low voltage noise (8 nV\/\u221aHz at 1 kHz), and low input current noise in a single device. The combination of low offsets, low noise, and very low input bias currents makes these amplifiers especially suitable for high-impedance sensor amplification and precise current measurements using shunts. The DC precision, low noise, and fast settling time (500 ns to 0.1%) result in superior accuracy for medical instruments, electronic measurement, and automated test equipment. Unlike many competitive amplifiers, the AD8513 maintains fast settling performance even with substantial capacitive loads. Unlike many older JFET amplifiers, it does not suffer from output phase reversal when input voltages exceed the maximum common-mode voltage range. The device is specified over the -40\u00b0C to +125\u00b0C extended industrial temperature range.","working_principle":"The AD8513ARUZ operates as a JFET-input precision operational amplifier with four independent channels in a single package. (1) Input Stage: The JFET input pair provides extremely low gate leakage current (25 pA typical), enabling high-impedance signal conditioning without loading the source. The JFET inputs also contribute to low voltage noise performance. (2) Gain Stage: The internal compensation network provides unity-gain stability while achieving a gain bandwidth product of 8 MHz. The amplifier maintains stability even with significant capacitive loads, which is critical for filter applications. (3) Output Stage: A class AB output stage delivers up to \u00b140 mA of output current with low distortion (0.0005% THD+N), suitable for driving both precision and audio loads. The output does not phase-reverse when the input common-mode range is exceeded, preventing latch-up conditions in feedback loops. (4) Bias and Reference: An internal bias network sets the operating point for each amplifier channel, with a typical supply current of 2.0 mA per amplifier. The PSRR of 130 dB and CMRR of 100 dB ensure robust rejection of power supply and common-mode variations.","pin_description":"
