ADCS7478AIMF/NOPB

The ADCS7478AIMF/NOPB is a low-power, monolithic CMOS 8-bit analog-to-digital converter (ADC) from Texas Instruments. It features a successive approximation register (SAR) architecture with an internal track-and-hold circuit, achieving a conversion rate of 1 MSPS. The device accepts a single-ended analog input with a full-scale range of 0V to VDD, using the supply voltage as the reference. It operates from a single 2.7V to 5.25V supply, consuming only 2 mW typical at 3V and 10 mW at 5V. The ADC provides a serial interface compatible with SPI, QSPI, MICROWIRE, and DSP interfaces. Key performance specifications include a typical signal-to-noise ratio (SNR) of 72.5 dB, differential nonlinearity (DNL) of +0.5/-0.3 LSB, and integral nonlinearity (INL) of ±0.4 LSB. The device is housed in a compact 6-pin SOT-23 package (2.9mm x 2.8mm) for surface-mount assembly. It is designed for applications requiring small size and low power consumption, such as portable instrumentation, data acquisition systems, and industrial control. The operating temperature range is -40°C to 85°C.
