decoder input (R) N.R.

Key Features

  • Reduction by power consumption of approximately 35% as compared with conventional products, contributing to low power consumption of a set.
  • Eliminating the DC/DC converter so far needed for conventional system due to 1.5 V single power supply, and reducing approx. 40% of external components. This contributes to space saving in a set.
  • Built-in standby switch to reduce consumption current considerably. Seating plane 0.15.
  • 0.05 +0.10 (1.00) LQFP048-P-0707 s.

ICs for Radio-Cassette, Cassette Deck AN7500FHQ Audio signal processing IC for 1.5 V headphone stereo s Overview The AN7500FHQ is a single chip IC optimum for a 1.5 V headphone stereo system including pre-amp., power amp. and Dolby B type noise reduction circuit. Current consumption in a Dolby circuit off mode has been drastically reduced and an operating supply voltage has also been lowered to 0.98 V. Much fewer external components have been realized due to an integration of audio signal processing system into a single chip circuitry in a small outline package and space saving mounting of a set. 9.00±0.40 7.00±0.20 36 37 25 24 (0.75) 7.00±0.20 9.00±0.40 13 1 12 0.20–0.05 +0.10 Unit: mm 48 (0.75) 0.50 (0.625) 1.40±0.10 1.70 max.
