The MAX4940CTN+ by Analog Devices is a high-density, quad-channel, high-voltage digital pulser IC. It generates unipolar or bipolar pulses from low-voltage logic inputs, offering output voltages from 0 to +220V unipolar or ±110V bipolar. The device features independent logic inputs and high-voltage pulser outputs with active clamps.
Key electrical specifications include a typical output impedance of 8.5 Ohms for the high-voltage outputs and 21 Ohms for the active clamp. The high-voltage outputs can deliver up to 2.0A of typical output current. The MAX4940CTN+ operates over a commercial temperature range of 0°C to +70°C and requires an operating voltage between 2.37V and 6V.
This IC is suitable for applications such as Ultrasound Medical Imaging, Flaw Detection, Piezoelectric Drivers, Test Instruments, and Cleaning Equipment. It is supplied in a 56-pin, 8mm x 8mm, TQFN exposed pad package, designed for surface mounting.
All digital inputs are CMOS compatible. The device does not require special power-supply sequencing for trilevel applications and features matched rise/fall times and matched propagation delays.
