Linear Systems High Voltage Super-Beta Monolithic Dual NPN
The LS313 is a monolithic pair of NPN transistors mounted in a single P-DIP package. The monolithic dual chip design reduces parasitics and gives better performance while ensuring extremely tight matching. The 8 Pin P-DIP provides ease of manufacturing, and the symmetrical pinout prevents improper orientation.
FEATURES HIGH GAIN hFE ≥ 400 @ 10µA‐1mA TIGHT VBE MATCHING |VBE1 – VBE2 |= 0.2mV TYP. HIGH ft 250MHz TYP. @ 1mA
◾ Very high gain ◾ Tight matching ◾ Low Output Capacitance
The DS32kHz is a temperature-compensated crystal oscillator (TCXO) with an output frequency of 32.768kHz. This device addresses applications requiring better timekeeping accuracy, and can be used to drive the X1 input of most Dallas Semiconductor real-time clocks (RTCs), chipsets, and other ICs containing RTCs. This device is available in commercial (DS32kHz) and industrial (DS32kHz-N) temperature versions.
