Dual 4-Channel Driver with Oscillator

ENA pin enables the chip, while the SEL1 pin selects the

amplitude is determined by the currents flowing into I

at OUTEN2, OUTEN3, and OUTEN4. The oscillator is

enabled when OSCEN is high. The amplified I

the selected channel is enabled when the ENA pin is high.

The total output current is the sum of the read current, the

enabled write currents, and the oscillator current when

enabled.

Usually a voltage DAC will drive a resistor that is in series

with the I

the user to optimize the current gain for each channel.

Output write current pulses are enabled when a low is

applied to the OUTEN2, OUTEN3, or OUTEN4 pin. The

write current will flow to the selected output. When SEL1 is

high I
