J10 – ANYOUT2 The channel-2 output voltage of the TPS7A89 is selectable in accordance with the names given to the output voltage setting pins: 50 mV, 100 mV, 200 mV, 400 mV, 800 mV, 1.6 V, and 1.6 V. For each pin connected to the ground, the output voltage setting increases by the value associated with that pin name, starting from the value of the reference voltage of 0.8 V;... - Page 5 J11 – ANYOUT1 The channel-1 output voltage of the TPS7A89 is selectable in accordance with the names given to the output voltage setting pins: 50 mV, 100 mV, 200 mV, 400 mV, 800 mV, 1.6 V, and 1.6 V.
