1-Bit, 10MHz, 2nd-Order, Isolated Delta-Sigma Modulator

The AMC1203 is a 1-bit, 10MHz, isolated delta-sigma ( ) Modulator with an output Buffer separated from the input Interface circuitry by a silicon dioxide (SiO 2 ) isolation barrier. This barrier provides galvanic isolation of up to 4000V PEAK . Used in conjunction with isolated power supplies, these devices prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. The AMC1203 Modulator operates from a +5V supply with a dynamic range of 95dB. The differential inputs are ideal for direct connection to shunt resistors or other low-level signal sources. With the appropriate digital Filter and Modulator rate, the device CAN be used to achieve 16-bit Analog-to-digital (A/D) conversion with no missing codes. An effective resolution of 14 bits and an SNR of 85dB (typical) CAN be maintained with a sinc 3 Filter with a decimation ratio of 256. The Modulator output is translated to a balanced signal and then transferred by the capacitive isolation barrier. Across the isolation barrier, a differential Comparator receives the Logic transition information, and then sets or resets a Flip-Flop and the output circuit accordingly. The AMC1203 is available in an SO-8 gull-wing package. SO-8 and SO-16 packages are planned for release in 2008. The AMC1203 is characterized for operation over the ambient temperature range of 40 C to +105 C. By Texas Instruments
