AD8021ARZ Low Noise High Speed Operational Amplifier IC Chip with 560 MHz Bandwidth SOIC-8

AD8021ARZ is an exceptionally high performance, high speed voltage feedback amplifier designed for 16-bit resolution systems. It features both low voltage and low current noise (2.1 nV/√Hz typical and 2.1 pA/√Hz typical) while operating at the lowest quiescent supply current (7 mA @ ±5 V) among today's high speed, low noise op amps.

The amplifier operates over a wide range of supply voltages from ±2.25 V to ±12 V, as well as from single 5 V supplies, making it ideal for high speed, low power instruments. An output disable pin allows further reduction of the quiescent supply current to 1.3 mA.

• Low noise: 2.1 nV/√Hz input voltage noise, 2.1 pA/√Hz input current noise
• Custom compensation: Constant bandwidth from G = -1 to G = -10
• High speed: 200 MHz (G = -1), 190 MHz (G = -10)
• Low power: 34 mW or 6.7 mA typ for 5 V supply
• Low distortion: -93 dBc second harmonic, fc = 1 MHz; -108 dBc third harmonic, fc = 1 MHz
• DC precision: 1 mV max input offset voltage, 0.5 µV/°C input offset voltage drift
• Wide supply range: 5 V to 24 V
