Part Details:

Isolated Sigma-Delta Modulator AD7400 FEATURES GENERAL DESCRIPTION 10 MHz clock rate The AD74001 is a second-order, sigma-delta (-) modulator Second-order modulator that converts an analog input signal to a high speed, 1-bit data 16 bits no missing codes stream with on-chip digital isolation based on Analog Devices, ±2 LSB INL typical at 16 bits Inc. iCoupler® technology. The AD7400 operates from a 5 V 3.5 V/°C maximum offset drift power supply and accepts a differential input signal of ±200 mV On-board digital isolator (±320 mV full scale). The analog input is continuously sampled On-board reference by the analog modulator, eliminating the need for external Low power operation: 18 mA maximum at 5.25 V sample-and-hold circuitry. The input information is contained -40°C to +105°C operating range in the output stream as a density of ones with a data rate of 16-lead SOIC package 10 MHz. The original information can be reconstructed with an Safety and regulatory approvals appropriate digital filter. The serial I/O can use a 5 V or a 3 V UL recognition supply (VDD2). 3750 V rms for 1 minute per UL 1577 The serial interface is digitally isolated. High speed CMOS, CSA Component Acceptance Notice #5A combined with monolithic air core transformer technology, VDE Certificate of Conformity means the on-chip isolation provides outstanding performance DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 characteristics superior to alternatives such as optocoupler VIORM = 891 V peak devices. The part contains an on-chip reference. The AD7400 is APPLICATIONS offered in a 16-lead SOIC and has an operating temperature AC motor controls range of -40°C to +105°C. Data acquisition systems An external clock version, AD7401, is also available. A/D + opto-isolator replacements 1 Protected by U.S. Patents 5,952,849; 6,873,065; and 7,075,329. Other patents pending.
