The gain of it is fixed to 6 dB (±0.
5 dB) with a small dispersion among the products.
• 3.
3 V supply voltage is available due to an external PNP-tr.
• Driver I/O gain setting is possible with an additional external resistor • Since the output and input lines are separated and respectively collected together, pattern designing is relatively easy.
