产品详情资料

模拟结果表明，当放大器配置为7V/V的增益时，在工艺变化的标准偏差内，相位裕度差小于1°。OPA858的主要应用之一是作为高速跨阻抗放大器（TIA），如图59所示。TIA的低频噪声增益为0dB（1V/V）。在高频下，总输入电容和反馈电容的比率设置了噪声增益。为了大化TIA闭环带宽，反馈电容通常小于输入电容，这意味着高频噪声增益大于0 dB。因此，配置为TIA的运算放大器不需要单位增益稳定，这使得去补偿放大器成为TIA的可行选择。关于跨阻抗放大器，您需要了解的内容-1部分和关于跨阻抗功放，您需要知道的内容–2部分更详细地描述了跨阻抗放大器补偿。图50.开环增益与温度图51.开环增益vs过程变化9.3.4转换速率和输出级除了宽带宽外，OPA858还具有2000 V/µs的高转换速率。转换速率是具有窄亚10 ns脉冲的高速脉冲应用中的关键参数，如光时域反射仪（OTDR）和激光雷达。OPA858的高转换速率意味着该设备准确地再现2-V，The simulated results suggest less than 1° of phase margin difference within a standard deviation of process variation when the amplifier is configured in a gain of 7 V/V. One of the primary applications for the OPA858 is as a high-speed transimpedance amplifier (TIA), as Figure 59 shows. The low-frequency noise gain of a TIA is 0 dB (1 V/V). At high frequencies the ratio of the total input capacitance and the feedback capacitance set the noise gain. To maximize the TIA closed-loop bandwidth, the feedback capacitance is typically smaller than the input capacitance, which implies that the high-frequency noise gain is greater than 0 dB. As a result, op amps configured as TIAs are not required to be unity-gain stable, which makes a decompensated amplifier a viable option for a TIA. What You Need To Know About Transimpedance Amplifiers – Part 1 and What You Need To Know About Transimpedance Amplifiers – Part 2 describe transimpedance amplifier compensation in greater detail.

Open-Loop Gain vs Process Variation 9.3.4 Slew Rate and Output Stage In addition to wide bandwidth, the OPA858 features a high slew rate of 2000 V/µs . The slew rate is a critical parameter in high-speed pulse applications with narrow sub 10-ns pulses such as Optical Time-Domain Reflectometry (OTDR) and LIDAR. The high slew rate of the OPA858 implies that the device accurately reproduces a 2-V,
