9 Power Supply Recommendations
Supply voltage is 4.4 V to 16 V for single supply and ±2.2 V to ±8 V for dual. In the high-side sensing application,
the supply is connected to a 12-V battery.
10 Layout
10.1 Layout Guidelines
The TLC227x-Q1 is a wideband amplifier. To realize the full operational performance of the device, good high
frequency printed-circuit-board (PCB) layout practices are required. Low-loss 0.1-μF bypass capacitors must be
connected between each supply pin and ground as close to the device as possible. The bypass capacitor traces
must be designed for minimum inductance.
