Low-cost amplifier provides headroom to prevent audio holesPaul OShea
I would have loved to have even a 2-band EQ in place of the shape knob. For those that rely on a clean tone, the headroom of the 15-watt amp is limited at lower gain settings. This head was made to rock out, so if you’re looking for a clean pedal platform, look elsewhere. ...
8.3.2 Slew Rate The slew rate is the rate at which an operational amplifier can change the output when there is a change on the input. These devices have a 20-V/μs slew rate. 8.4 Device Functional Modes These devices are powered on when the supply is connected. These devices can be...

This additional offset should not hinder the performance of the THS7313 as there is still plenty of voltage headroom between the dc operating point and the rail-to-rail output capability. One possible concern about this configuration is the low frequency gain enhancement may cause saturation of ...
Finding an op amp for the gain stage that has low Ib, reasonably low Is, and can operate with 2-2.5 V headroom on V+ took a lot of data sheet reading. I was a bit nervous that the poor LF noise performance of the OPA1655 would show through, but the gain of the input diff pair...
This is necessary because the instrumentation amplifier requires headroom to ensure that signals close to GND or AVDD are converted accurately. The bias voltage generator is controlled using the VBIAS1 and VBIAS0 bits in conjunction with the boost bit in the configura- tion register. The power-...
VHP settings lower than VA reduces the headroom of the headphone amplifier. As a result, the DAC may not achieve the full THD+N performance at full-scale output voltage and power. AOUTx AGND 51 Ω 0.022 μF CL RL Figure 2. Headphone Output Test Load 14 DS792F2 Confidential Draft 3/...
The usable input common-mode range of the front-end depends on various parameters, including the maximum differential input signal, supply voltage, PGA gain, and the 200 mV for the amplifier headroom. This range is described in Equation 4: AVDD - 0.2 V - æ Gain ççè ´ VMAX _ ...
The buffers require 100 mV of headroom. The reference voltage of REFIN (REFINx(+) − REFINx(−)) is 2.5 V nominal, but the AD7124-4 is functional with reference voltages from 0.5 V to AVDD. In applications where the excitation (voltage or current) for the transducer on the analog ...
