DESCRIPTION
THAT series large-geometry, 4-transistor, monolithic and/or arrays exhibiting both high speed noise, with excellent parameter matching between transistors same gender. With typical base-spreading resistances ohms devices ohms NPNs), their resulting voltage noise under nV/root-Hz makes series ideally suited low-noise amplifier input stages, among other applications. Fabricated dielectrically isolated, complementary bipolar process, each transistor electrically insulated from others layer insulating oxide (not reverse-biased junctions used conventional arrays) exhibit inter-device crosstalk isolation similar that expected from discrete transistors. resulting collector-to-substrate capacitance produces typical (325 PNPs). Substrate biasing required normal operation, though substrate should grounded optimize speed minimize crosstalk. eight-transistor bare-die array with similar performance characteristics (the THAT 380G) also available from THAT Corporation. Please contact directly through your local distributor more information.

Information furnished THAT Corporation believed accurate reliable. However responsibility assumed THAT Corporation it's infringements patents other rights third parties which result from it's use. LIFE SUPPORT POLICY THAT Corporation products designed life support equipment where malfunction such products reasonably expected result personal injury death. buyer uses sells such products life suport application buyer's risk agrees hold harmless THAT Corporation from damages, claims, suits expense resulting from such use. CAUTION: THIS (ELECTROSTATIC DISCHARGE) SENSITIVE DEVICE. damaged currents generated electrostatic discharge. Static charge therefore dangerous voltages accumulate discharge without detection causing loss function performance occur. transistors this device unprotected order maximize performance flexibility. They more sensitive damage than many other which include protection devices their inputs. Note that pins (not just "inputs") susceptible. preventative measures when storing handling this device. Unused devices should stored conductive packaging. Packaging should discharged destination socket before devices removed. damage occur these devices even after they installed board-level assembly. Circuits should include specific appropriate protection.
