al {> Cc sM6011 NIPPON PRECISION CIRCUITS LTD. High-speed Data Converter eee OVERVIEW PINOUT The SM6011 is a high-speed data converter fabri- cated in Molybdenum-gate CMOS. It comprises pe [2a] 01 one 8-bit A/D converter, which uses a half-flash os [2] 00 conversion method, and two 8-bit voltage-output ba [ze] voo D/A converters. The A/D converter does not require [al fal an external sample-and-hold circuit. Digital data ee a can easily be interfaced with the data bus of com- ve [| [za] seu mon CPUs. oe [el g s [23] ave n +) The SM6011 is available in 28-pin plastic DIPs and o 8 a wo 28-pin SOPs. oe gs wo reno [es] BG [20] A FEATURES a Ll pre {1a] oS = A/D converter onc) [12] wa * 8-bit resolution ow) [19] [16] 40 + 1.0 ps (max) conversion time DAI [as] at + Intemal sample-and-hold circuits not required + Built-in 2-channel multiplexer = D/A converter + 8-bit resolution * 2.5 us (max) settling time + Voltage output waveform + 2 channels = Internal clock not required = Low power consumption ™ Can be connected directly to a CPU = Single 5 V supply = 28-pin plastic DIP and 28-pin SOP ™ Molybdenum-gate CMOS process a NIPPON PRECISION CIRCUITS—1
