ADS7886SBDCKT

The ADS7886SBDCKT is a 12-bit, 1-MSPS successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It features a single-ended input with a unipolar input range of 0 V to VDD, and a SPI-compatible serial interface. The device operates from a single supply voltage range of 2.35 V to 5.25 V for both analog and digital supplies, making it suitable for low-power applications.

Key performance specifications include a typical signal-to-noise ratio (SNR) of 72.25 dB, integral nonlinearity (INL) of ±0.65 LSB typical (±1.25 LSB maximum), and differential nonlinearity (DNL) of +0.4/−0.65 LSB typical (±1 LSB maximum). Power consumption is 3.9 mW at 3 V and 7.5 mW at 5 V when sampling at 1 MSPS, with a power-down current of only 1 µA.

The ADC offers zero latency and a wide input bandwidth of 15 MHz at −3 dB, enabling accurate conversion of high-frequency signals. It is designed for applications requiring small size and low power, such as portable instrumentation, sensor interfaces, and battery-powered systems.

The device is available in a 6-pin SC-70 (SOT-SC70) package with dimensions of 2 mm × 2.1 mm, and also in a SOT-23 package. It is surface-mountable and operates over the industrial temperature range of −40°C to 125°C.
