The LF198H by Advanced Micro Devices is a monolithic sample-and-hold circuit designed for high DC accuracy and fast signal acquisition. Utilizing BI-FET technology, it achieves a typical gain accuracy of 0.002% and an acquisition time as low as 6 µs to 0.01%.
This device operates from ±5V to ±18V supplies and features TTL, PMOS, and CMOS compatible logic inputs. The input impedance is 10 GΩ, allowing for high source impedances without degrading accuracy. The output amplifier uses P-channel junction FETs combined with bipolar devices, resulting in low droop rates.
The LF198H is suitable for applications requiring precise signal holding. Its wide bandwidth allows integration into feedback loops of high-frequency operational amplifiers without stability issues. The component is available in various packages, including H, N, and M types, with specific operating temperature ranges for each variant.
