In a world with plenty of low-noise JFET input op-amps, who would have thought anyone would still be introducing a discrete dual JFET. Well, TI did in August: the JFE2140. Its target is high-end audio amplifiers. Thoughtfully integrated with lots of clamping diodes (12 of them), the pair achieves: 0.9nV/√Hz voltage noise (1kHz, 5mA Ids) 1.1nV/√Hz …
