This series features tightly matched specs, low gate leakage for accuracy, and wide dynamic range with I G guaranteed at V DG = V. The hermetically-sealed TO-7 package is available with full military processing (see Military Information and the N/6/7JANTX/JANTXV data sheet). For similar products see the low-noise U/SST series, the high-gain N9/9, and the low-leakage U/ data sheets. TO-7 S G 6 D D G S Top View Gate-Drain, Gate-Source Voltage...............................
