The ADA4077-2 has a typical bandwidth of 3.9 MHz and 7-nV/√Hz voltage noise at 1 kHz while consuming only 400 A typical at 25C with 15-Vdc nominal power supplies. Available in two grades for offset and thermal drift, the device provides design engineers with the flexibility to meet budget and packaging requirements.

Compared to its closest competition, the ADA4077-2 offers higher speed with lower noise, offset and drift while consuming less power, making the ADA4077-2 an ideal, cost-effective op amp for use in front end sensor interface in applications such as process control input modules, where high accuracy, precision, and linearity are critical to accurate measurement of sensor output.

ADA4077-2 Precision Operational Amplifier Key Features:
• Low offset voltage: 25V maximum (B-Grade)
• Low offset voltage drift: 0.25 V/C maximum (B-Grade)
• Low input bias current: <1.0 nA maximum
• Input voltage range: V- +1.2 V to V+ -2 V
• Low noise: 7 nV/√Hz typical
• Low supply current: 400 A per amplifier typical
• Specified for dual voltage supply operation from 5 V to 15 V
