General Description
The HV276 is a 16-channel, high-voltage amplifier
array. Each channel consists of a low-voltage digital-toanalog
converter and a fixed-gain high-voltage operational
amplifier. The DAC has 11-bit resolution, and the
DAC output is connected to the fixed-gain high-voltage
operational amplifier with a maximum output voltage
swing of ±75 V for a 250 pF capacitive load.
Each receive channel has its own internal detection circuit
and individual receiver to validate the data from the
serial-to-parallel interface using the SAFETY control
signal and its protocol.
This device consists of 16 11-bit shift registers, control
logic functions and Power-on Reset (POR). Four power
supplies are required, ±5.0V and ±90V. An external
3.0V voltage reference is needed for precision output.
The system supports both 3.3 V or 2.5 V logic input.
