Hello-- I located another batch of various audio-related D/A and A/D ICs for SDR experimentation. Quantities are limited where so stated, and components are reserved for first inquirer(s) pending payment. *** Burr-Brown PCM1710U dual D/A Converter IC; resolution = 20 bits at an update rate of 48 K samples per second max. Serial and parallel interfaces. 5V power supply; 28-pin SOIC package. 1994 date codes. Approx. 72 pcs. available at $1.00 each, or 12 pcs. for $10.00 *** Crystal Semiconductor CS4329-KS dual D/A converter. Resolution = 20 bits at an update rate of up to 48 K SPS. Multiple serial-data input modes. 20-pin SSOP package. Only two pieces available in UNOPENED distributor-sealed moisture-resistant foil pkg., with dessicant packet enclosed. Here's a user's application note:
www.audiocraftersguild.com/AandE/protodac.pdf Asking $8.00 for the pair. *** Asahi Kasei (AKM Semiconductor) AK5352 20-bit, 96kHz sampling rate for DAT and DVD, 64x oversampling rate (64fs), 2-channel A/D converter. 24-pin VSOP pkg. Only two pcs. available-- asking $8.00 for the pair. *** The AK4117 is a S/PDIF AES/EBU receiver supporting sample rates up to 192kHz and resolution up to 24-bit. 24-pin VSOP pkg. Only 5 pcs. available at $4.00 each. *** PMI (now Analog Devices) SSM2402P dual SPST analog switches.Designed for low noise and distortion over the audio range 20 Hz-20 kHz) at signal levels up to 10 VRMS. 14-pin plastic DIP. 10 pcs. available at $1.00 each. *** 2SC2878 NPN audio switching transistor, features unusually high base-emitter reverse-breakdown voltage (25V) and high reverse-biased gain (hFE approx. 150 at Vce = -2V, Ic = -4 mA). Low on-resistance (1 ohm) and Vce(sat) of 42 mV typical at Ic = 30 mA. TO-92 pkg. Buy 8 pieces for $1.00 *** First-class postage is extra, but typically costs approximately $3.00 for small-quantity orders shipped to U.S. addresses (overseas purchasers: please inquire for postage). I honor PayPal, personal checks drawn on U.S. banks, and U.S.P.S. or bank-issued money orders. Data sheets are available for most items, and I welcome questions. 73-- Brad AA1IP Brad Thompson P.O.
