LM7131

LM7131 Tiny High Speed Single Supply Operational Amplifier September 1999 LM7131 Tiny High Speed Single Supply Operational Amplifier General Description 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. Single supply voltages of 3V and 5V provides good video performance, wide bandwidth, low distortion, and high PSRR and CMRR. This makes the amplifier an excellent choice for desktop and portable video and computing applications. The amplifier is supplied in surface mount 8-pin and tiny SOT23-5 packages. Tiny amplifiers are so small they can be placed anywhere on a board close to the signal source or next to an A-to-D input. Good high speed performance at low voltage makes the LM7131 a preferred part for battery powered designs. n n n n n n n n n Guaranteed specs at 3V, 5V, and ± 5V supplies Typical supply current 7.0 mA at 5V, 6.5 mA at 3V 4V output swing with +5V single supply Typical total harmonic distortion of 0.1% at 4 MHz 70 MHz Gain-Bandwidth Product 90 MHz −3 dB bandwidth at 3V and 5V, Gain = +1 Designed to drive popular video A/D converters 40 mA output can drive 50Ω loads Differential gain and phase 0.25% and 0.75˚ at AV = +2 Applications n n n n n Driving video A/D converters Video output for portable computers and PDAs Desktop teleconferencing High fidelity digital audio Video cards Features n Tiny SOT23-5 package saves space-typical circuit layouts ta...
