Three blocks are offered at this time: 1) 3A, 24V transmitter capable of driving low impedance loads down to 1 Ohm, 2) RX with range of 48dB to -12dB of total gain with a high voltage input, and 3) a precision bias circuit used to provide each the above circuits with the required reference currents. Take a look at the data sheets in the IP section. Email or call us for additional information.
