ADVANCE INFORMATION for pre-production products; subject to change without notice.
The OPA818 is a 13 V supply, 2.7 GHz gain-bandwidth product (GBWP), voltage feedback operational amplifier (op amp) featuring a 2.2nV/√Hz low noise JFET input stage. The OPA818 is decompensated to be normally stable in gains ≥ 7 V/V. The decompensated architecture allows for a favorable tradeoff of low quiescent current for a very high GBWP and low distortion performance in high gain applications. The high voltage capability combined with 1400 V/µs slew rate enables applications needing wide output swings (10 VPP at VS = 12 V) for high frequency signals such as those often found in optical front-end, test and measurement applications, and medical systems. The low noise JFET input with pico amperes of bias current makes the device particularly attractive for high transimpedance gain TIA applications and for test and measurement front-ends. OPA818 also features power down mode that disables the core amplifier for power savings.
OPA818 is built using TI's proprietary high-voltage high-speed complementary bipolar SiGe process.
