Texas Instruments AMC1203

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 (sio2) isolation barrier. this barrier provides galvanic isolation of up to 4000vpeak. 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. view all in datasheet
