AD8138ARMZ Differential ADC Driver
Ultra-Low Distortion meets 320MHz High Speed – The Professional Differential Op-Amp Choice for High-Resolution ADC Interfacing.
// High-Performance SFDR -94dBc @ 5MHz System Core Portfolio
The High-Speed Differential Signal Advantage
The AD8138ARMZ represents a premier flagship solution for space-constrained, high-frequency embedded systems demanding absolute harmonic linearity and balanced differential driving capabilities. Engineered by Analog Devices, this differential amplifier scales signal conversion fidelity by expanding its massive 320MHz bandwidth and reducing total harmonic distortion to -94dBc at 5MHz. Housed in a low-inductive 8-lead MSOP package layout, it secures deterministic parallel computing and clutter-free signal transmission paths for premium high-speed ADCs.
- 320 MHz large-signal bandwidth (-3dB) providing crisp signal reproduction
- Internal common-mode feedback loops ensuring perfectly balanced differential outputs
- Extremely low harmonic distortion filtering parasitic cross-talk noise paths
Key Performance Advantages
320MHz Broad Bandwidth
Maintains excellent high-speed dynamic tracking capabilities, enabling fast pulse conversions inside automated telecom and data log mainplates.
Ultra-Low Distortion
Delivers SFDR of -94dBc at 5MHz, successfully preventing phase noise anomalies from skewing high-resolution 14-bit to 16-bit analog-to-digital matrix grids.
Micro-Scale MSOP-8
Housed in an incredibly small 8-lead MSOP footprint package outline, minimizing localized board real-estate inside high-density multi-channel sensors.
