Sutter Instrument is proud to introduce the latest cutting-edge tool for electrophysiology research, the dPatch® Digital Patch Clamp Amplifier. Using high-speed digital processing, matched with high-resolution data converters and paired with SutterPatch® software’s intuitive user interface, this low-noise, high-bandwidth precision instrument provides capabilities previously unavailable to electrophysiologists.
Available in either a single- or dual-headstage configuration, the dPatch amplifier’s architecture makes swapping headstages, or adding a second one to a single-headstage version, a plug-and-play operation. The two headstages are independently configurable for either voltage clamp or true high-speed current clamp. Data is streamed from each headstage in parallel and fully synchronized.
5 MHz SAMPLING RATE, UP TO 22-BIT RESOLUTION
One unique feature with dPatch is the headstage data sampling system. Each headstage is continually sampled at 5 MHz. Output filtering has thirteen settings between 100 Hz and 1 MHz. A resolution of 18 bits is achieved at 1 MHz. For lower filter settings, automatic downsampling increases resolution while optimizing data rates. At a bandwidth setting of 1 kHz, the dPatch system provides a signal resolution of better than 22 bits.
