Renesas | ISL28191FHZ-T7

The ISL28191FHZ-T7 is a single channel ultra-low noise, ultra-low distortion operational amplifier. It is available in 6 pin SOT-23 package.

This device is fully specified to operate down to +3 V single supply. It has outputs that swing rail-to-rail and an input common mode voltage that extends to ground. It is a unity gain stable with an input referred voltage noise of 1.7 nV/√Hz. Both parts feature 0.00018% THD+N at 1 kHz.

Features:

• 1.7 nV/√Hz input voltage noise at 1 kHz
• 1 kHz THD+N typical 0.00018% at 2VP-P VOUT
• Harmonic Distortion -76dBc, -70dBc, fo = 1 MHz
• 61 MHz -3dB bandwidth
• 630 μV maximum offset voltage
• 3 μA input bias current
• 100 dB typical CMRR
• 3 V to 5.5 V single supply voltage range
• Rail-to-rail output
• Ground Sensing
• Enable pin (not available in the 8 Ld SOIC package option)
• Pb-free (RoHS compliant)

Applications:

• Low noise signal processing
• Low noise microphones/preamplifiers
• ADC buffers
• DAC output amplifiers
