LT1819CS8#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1819CS8#PBF is a dual operational amplifier manufactured by Analog Devices Inc. It features a gain bandwidth product of 400MHz and a slew rate of 2500V/µs. The device operates on supply voltages ranging from ±2V to ±6V, drawing a typical supply current of 9mA per amplifier. It provides low harmonic distortion of –85dBc at 5MHz for a 2VP-P output signal. The input noise voltage density is 6nV/√Hz, with a maximum input offset voltage of 3.0mV over the industrial temperature range. The component is housed in an 8-lead plastic SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix #PBF corresponds to lead-free finish specifications as defined in the manufacturer's documentation. Confirm the 'CS8' designation aligns with the commercial temperature grade (0°C to 70°C) rather than the industrial grade. Ensure the 8-lead SOIC package dimensions match the required PCB footprint constraints before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual channel configuration is required alongside the performance metrics of the single-channel LT1818. The LT1819 offers identical electrical characteristics including bandwidth and noise but integrates two amplifiers in one package. Consider the 8-lead SOIC package availability if surface mount space allows for standard narrow outline dimensions compared to smaller alternatives like MSOP.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1818/LT1819 family of wide bandwidth, high slew rate operational amplifiers. The LT1819 specifically denotes the dual amplifier variant, whereas the LT1818 is the single channel version. Both share the same underlying complementary bipolar process technology designed for low noise and distortion performance relative to their supply current consumption.
