The devices are fully specified over the extended industrial range to +105вЊ) and are available an HTQFP-64 PowerPADTM package. All operations are controlled directly by pins there are no registers to program. Four operating modes allow for optimization of speed, resolution, and power. These ADCs provide a usable signal bandwidth 90% of the Nyquist rate with less than 0.005dB of ripple. The onboard decimation filter suppresses modulator and signal out-of-band noise. The high-order, chopper-stabilized modulator achieves very low drift with low in-band noise. The ADS1274 and ADS1278 combine these types of converters, allowing high-precision industrial measurement with excellent dc and ac specifications. High-resolution ADCs in audio applications offer larger usable bandwidths, but the offset and drift specifications are significantly weaker than respective industrial counterparts. As a result, they have limited signal bandwidth and are mostly suited for dc measurements. Traditionally, industrial delta-sigma ADCs offering good drift performance use digital filters with large passband droop. The devices are offered in identical packages, permitting drop-in expandability. These labs have built in DC Power Supplies, Pulse Generator, Pulser Switches, Data Switches, Logic Probe, Digital Display, TTL/CMOS Mode Selector, and LED Display.Simultaneously Measure Four/Eight Channels to 128kSPS Data Rate AC Performance: 62kHz Bandwidth 111dB SNR (High-Resolution Mode) В108dB THD DC Accuracy: 0.8V/вЊ Offset Drift 1.3ppm/вЊ Gain Drift Selectable Operating Modes: High-Speed: 128kSPS, 106dB SNR High-Resolution: 52kSPS, 111dB SNR Low-Power: 52kSPS, 31mW/ch Low-Speed: 10kSPS, 7mW/ch Linear Phase Digital Filter SPITM or Frame-Sync Serial Interface Low Sampling Aperture Error Modulator Output Option (digital filter bypass) Analog Supply: 5V Digital Core: 1.8V I/O Supply: to 3.3VД«ased on the single-channel ADS1271, the ADS1274 (quad) and ADS1278 (octal) are 24-bit, delta-sigma analog-to-digital converters (ADCs) with data rates to 128k samples per second (SPS), allowing simultaneous sampling of four or eight channels.

The boards can be used as standalone unit with external DC Power Supply and logic data switches, or can be used with Scientech Digital Labs Scientech 2611/Scientech 2614. Test points are provided to observe the waveforms/ signals and to measure voltages at different nodes. Logic diagrams on the boards provide easy understating of the concepts. The boards are very user friendly and support self learning through flexibility of making circuit connections. Scientech Digital Electronics Experiment Boards are designed as a comprehensive Modular solution for beginners to explore the fundamentals of a variety of basic building blocks in Digital Electronics.
