Frequently Asked Questions
What is the resolution and sampling speed of the ADS7818E/250?
The ADS7818E/250 is a 12-bit ADC with a maximum sampling rate of 250kSPS (kilo-samples per second). It delivers ±0.5 LSB DNL and ±1 LSB INL, making it suitable for precision data acquisition applications.
What interface does the ADS7818E/250 use?
The ADS7818E/250 uses a serial SPI/QSPI/MICROWIRE-compatible interface, enabling easy connection to microcontrollers and DSPs with minimal pin count. It requires only SCLK, DOUT, and CS signals.
What are the supply voltage requirements for the ADS7818E/250?
The ADS7818E/250 operates from a single 5V supply (4.75V to 5.25V) and consumes approximately 12mW at full sampling speed. It supports auto power-down between conversions to minimize average power in low-duty-cycle applications.
What is the package and operating temperature range?
The ADS7818E/250 is available in an 8-pin SOIC package with an industrial operating temperature range of -40°C to +85°C, suitable for harsh environments in industrial and automotive applications.
What are common alternatives to the ADS7818E/250?
Compatible alternatives include the ADS7816 (12-bit, 200kSPS), ADS7819 (12-bit, 500kSPS), and ADS8320 (16-bit, 100kSPS) from Texas Instruments, as well as the MAX1241 from Maxim Integrated with similar SPI serial output.
