Part Number: DRV8601
Reading the datasheet, in section 7.1 it references being able to accept a single-ended DC control voltage to provide a differential output. Can I drive a sensor coil (primary of an LVDT) directly from this device? For input to the device I can provide a DC linear signal referenced at the midpoint reference voltage.
My drive signal is a 2.4khz triangle wave, which I can center at the midpoint of the power range.
I'm driving the primary coil of a LVDT that has a 300-600 ohm impedance at that frequency range.
Reading through the chip description, this seems to exactly fit what I need, but there's not much mention of that capability in the datasheet.
Hi David, Can you clarify the application a little more? Are you trying to produce a DC output signal or a 2.4kHz output signal? This device was designed to drive haptic actuators in the frequency range of ~50-300Hz. Typical load resistances for haptic actuators are 8-30ohms.
