Condition

T=25°C, VCC=3.0V

Minimum frequency is dependent upon input

blocking cap, DC feedback cap, and gain

setting. Recommended components yields a

minimum frequency of less than 10kHz.

Driving a 5kΩ load

At maximum gain setting

Maximum RSSI is 2.5V or VCC-0.3, which-

ever is less.

Differential

Five pole Bessel internal LPF.

Three pole external LPF.

Selectable from 1MHz, 2MHz, 4MHz, and

8 MHz.

At 8MHz, increasing as bandwidth

decreases.
