The TLV904xD family includes single (TLV9041D) and dual (TLV9042D) decompensated operational amplifiers optimized for high efficiency in ultra-low-voltage applications. Operating from 1.2V to 5.5V with rail-to-rail input and output swing, this family of amplifiers deliver an exceptional gain bandwidth of 3.1MHz with only 16µA of quiescent current. The TLV904xD enables high gain circuit configurations and longevity in battery powered systems. The availability of miniature packages also allow this amplifier family to be used effectively in high density board applications.

The TLV904xD is among the few amplifiers in the industry capable of operating at supply voltages as low as 1.2V, making the family well suited for 1.5V coin cell applications. The high gain bandwidth eliminates the need for cascaded amplifier stages in signal conditioning and filtering applications such as field transmitters, motion detectors, and personal electronics, simplifying design while reducing both board space and overall system power consumption.

ANALOG-ENGINEER-CALC — 模拟工程师计算器

模拟工程师计算器旨在加快模拟电路设计工程师经常运用的许多重复性计算。该基于 PC 的工具提供图形界面,其中显示各种常见计算列表,从使用反馈电阻器设置运算放大器增益到选择合适的电路设计元件,以稳定模数转换器 (ADC) 驱动器缓冲器电路。

除了可用作独立工具之外,该计算器还能很好地与模拟工程师口袋参考中所述的概念配合使用。

设计工具

CIRCUIT060013 — 采用 T 网络反馈电路的反相放大器

该设计将输入信号 VIN 反相并应用 1000V/V 或 60dB 的信号增益。具有 T 反馈网络的反相放大器可用于获得高增益,而无需 R4 具有很小的值或反馈电阻器具有很大的值。
设计工具

CIRCUIT060015 — 可调节基准电压电路

该电路结合了一个反相和同相放大器,可使基准电压在正负输入电压范围内进行调节。可通过增加增益来提高最大负基准电压电平。
设计工具

CIRCUIT060074 — 采用比较器的高侧电流检测电路

该高侧电流检测解决方案使用一个具有轨到轨输入共模范围的比较器,如果负载电流上升至超过 1A,则在比较器输出端 (COMP OUT) 产生过流警报 (OC-Alert) 信号。该实现中的 OC-Alert 信号低电平有效。因此,当超过 1A 阈值后,比较器输出变为低电平。实施磁滞以确保在负载电流减小至 0.5A(减少 50%)时,OC-Alert 返回到逻辑高电平状态。该电路使用漏极开路输出比较器,从而对输出高逻辑电平进行电平转换,以控制数字逻辑输入引脚。对于需要驱动 MOSFET 开关栅极的应用,最好使用具有推挽输出的比较器。
