Each combines a 10-element LED array and a monolithic integrated circult display driver. Successive LEDs light as the analog input voltage level increases past prescaled threshold points. The TSM3914 provides a linear analog display, with in- ternal threshold points linearly sealed. A logarithmic display is provided by the TSM3915 with threshold points set on 3dB Intervals. The TSM3916 is a variation of the logarithmic display; the VU meter function is provided by using threshold points at common VU intervals. The driver circult contains an adjustable voltage refer- ence which precisely sets LED thresholds, Current drives to the LEDs are regulated and programmabie, eliminating the need for resistors. The entire display can operate from supply voltages as low as 3V and as high as 24V. The internal voltage reference is also connected to an accu- rate 10-step voltage divider, supplying reference voltages for 10 individual comparators. These comparators switch as the signal voltage exceeds the established thresholds as described aboye. The typical overall inaccuracy (deviation from ideal) is typically within 1% for the TSM3914 and below 1dB for the TSM3915 and TSM3916. A high Impedance input buffer accepts signais down to ground, yet protects against signal inputs of 35V above or below ground. A single (mode) pin changes the display fram a bar graph to a moving dot. THAEE-FIVE SYSTEMS, LTO. Swindon, U.K. TEL: (0793) 610935; FAX: (0793) 614127 THREE-FIVE SYSTEMS, INC.

The edge connector tab will withstand 230C for 5 seconds. Permanent damage to the display will result if reflector temperature exceeds 70C, Since the display is not hermetic, Immersion of the entire package during flux and clean operation may cause condensation of flux or cleaner on the underside of the reflector. Only the edge connectors should be immersed. Rosin core solder, solid core solder, and low activity organic fluxes are recommended. Freon TF, lsopropanol, Methano! or Ethanol solvents are recommended only at room temperature and for short periods. The use of other solvents or elevated temperature use of the recom- mended solvents may cause permanent damage to the reflector or display. | THREE-FIVE SYSTEMS, ING.
