The LM7131 is a high speed bipolar operational amplifier available in a tiny SOT23-5 package. This makes the LM7131 ideal for space and weight critical designs.
The LM7131 is a high speed bipolar operational amplifier designed for space and weight critical designs. It operates on single supply voltages of 3V and 5V, providing good video performance with wide bandwidth, low distortion, and high PSRR and CMRR. The device is supplied in surface mount 8-pin SO-8 and tiny 5-pin SOT23-5 packages.
The document provides guaranteed electrical characteristics for both DC and AC parameters at 3V and 5V supplies. Key specifications include a typical total harmonic distortion of 0.1% at 4 MHz, a gain-bandwidth product of 70 MHz, and a -3 dB bandwidth of 90 MHz. The amplifier is designed to drive popular video A/D converters.
| Gain-Bandwidth Product | 70 MHz |
|---|---|
| -3 dB Bandwidth (3V) | 90 MHz |
| -3 dB Bandwidth (5V) | 90 MHz |
| Typical Supply Current (5V) | 7.0 mA |
| Output Swing (+5V single supply) | 4V |
| Total Harmonic Distortion (Typical) | 0.1% at 4 MHz |
The typical supply current is 7.0 mA when operating at a +5V supply.
The amplifier provides an output swing of 4V when powered by a +5V single supply.
The device has a gain-bandwidth product of 70 MHz.
