Product Summary

The AD7874SQ is a four-channel simultaneous sampling, 12-bit data acquisition system. The AD7874SQ contains a high speed 12-bit ADC, on-chip reference, on-chip clock and four track/hold amplifiers. This latter feature allows the four input channels to be sampled simultaneously, thus preserving the relative phase information of the four input channels, which is not possible if all four channels share a single track/hold amplifier. This makes the AD7874SQ ideal for applications such as phased-array sonar and ac motor controllers where the relative phase information is important. The AD7874SQ is ideal for: (1)Sonar; (2)Motor Controllers; (3)Adaptive Filters; (4)Digital Signal Processing.

Parametrics

AD7874SQ absolute maximum ratings: (1)VDD to AGND: –0.3 V to +7 V; (2)VDD to DGND: –0.3 V to +7 V; (3)VSS to AGND: +0.3 V to –7 V; (4)AGND to DGND: –0.3 V to VDD + 0.3 V; (5)VIN to AGND: –15 V to +15 V; (6)REF OUT to AGND: 0 V to VDD; (7)Digital Inputs to DGND: –0.3 V to VDD + 0.3 V; (8)Digital Outputs to DGND: –0.3 V to VDD + 0.3 V; (9)Operating Temperature Range: Commercial (A, B Versions): –40℃ to +85℃; Extended (S Version): –55℃ to +125℃; (10)Storage Temperature Range: –65℃ to +150℃; (11)Lead Temperature (Soldering, 10 secs): +300℃; (12)Power Dissipation (Any Package) to +75℃: 1,000 mW; (13)Derates above +75°C by: 10 mW/℃.
