JFET-input audio op-amps
26 May 2010, Analogue, Mixed Signal, LSI
Extending its Burr-Brown Audio line, Texas Instruments has introduced a family of JFET-input op-amps featuring low noise and distortion to maximise audio system quality and performance. With a quiescent current of 1,8 mA per channel, the OPA1641, OPA1642 and OPA1644 support the multiple channels pro audio applications require, without increasing power consumption in high-performance audio circuits, such as broadcast studio equipment, analog and digital mixing consoles, and high-end A/V receivers.
The FET inputs deliver input bias current of just 2 pA, noise of 5 nV/√Hz and distortion of 0,00005% at 1 kHz. The devices’ wide supply voltage range of +2,5 V to +18 V and rail-to-rail output swing allow for increased headroom, which is critical for audio analog-to-digital converter (ADC) front ends and digital-to-analog converter (DAC) post filters. |
