⚖️ Comparison: RS8562XK matches or outperforms top-tier competitors in input bias current, ensuring high impedance compatibility and reduced loading for sensitive analog sources.

3. Voltage Noise Density (at 1 kHz)

• RS8562XK: 5.8 nV/√Hz

• LTC6241: 6 nV/√Hz

• AD8616: 22 nV/√Hz

✅ Advantage: RS8562XK delivers ultra-low voltage noise, outperforming both LTC6241 and AD8616, which translates into higher signal integrity for precision applications such as ECG front-ends, bridge sensors, and low-level ADC inputs.

4. Gain Bandwidth Product (GBP)

• RS8562XK: 18 MHz

• LTC6241: 18 MHz

• AD8616: 10 MHz

⚖️ Comparison: RS8562XK and LTC6241 offer similar bandwidth, while outperforming AD8616 by nearly 2×. The high GBP ensures excellent dynamic response in filtering, buffering, and active control loops.

5. Quiescent Current (per channel)

• RS8562XK: 1.6 mA (typical)

• LTC6241: 2.2 mA (typical)

• AD8616: 1.3 mA (typical)

✅ Advantage: RS8562XK provides a better balance between noise and power, achieving lower noise than AD8616 while consuming ~27% less power than LTC6241. This makes it particularly suitable for battery-powered precision systems.

6. Supply Voltage Range

• RS8562XK: 2.5 V to 5.5 V

• LTC6241HV variants: Up to ±5.5 V

• AD8616: 2.7 V to 5.5 V

⚖️ Comparison: While some LTC6241 variants support higher dual-supply ranges (e.g., ±5V), the RS8562XK is optimized for modern single-supply, low-voltage systems, covering the 2.5V to 5.5V range common in portable and digital systems.
