ADA4940-2ACPZ-R2 General Description
The ADA4940-1 / ADA4940-2 are low noise, low distortion differential amplifiers with very low power consumption. They are an ideal choice for driving low power, high resolution, high performance SAR and sigma-delta (Σ-Δ) analog-to-digital converters (ADCs) with resolutions up to 18 bits from dc to 1 MHz on only 1.25 mA of quiescent current. The adjustable level of the output common-mode voltage allows the ADA4940-1 / ADA4940-2 to match the input common-mode voltage of multiple ADCs. The internal common-mode feedback loop provides exceptional output balance, as well as suppression of even-order harmonic distortion products.
Features
- Small signal bandwidth: 260 MHz
- Ultralow power 1.25mA
- Extremely low harmonic distortion
- −122 dB THD at 50 kHz
- −96 dB THD at 1 MHz
- Low input voltage noise: 3.9 nV/√Hz
- 0.35 mV maximum offset voltage
- Balanced outputs
- Settling time to 0.1%: 34 ns
- Rail-to-rail output: −VS + 0.1 V to +VS − 0.1 V
- Adjustable output common-mode voltage
- Flexible power supplies: 3 V to 7 V (LFCSP)
- Disable pin to reduce power consumption
Application
- Low power ADC drivers
- Single-ended-to-differential converters
- Differential buffers
- Line drivers
- Medical Imaging
- Industrial Process Control
