ADC101S051CIMF

Analog To Digital Converters (ADC) Overview

The ADC101S051CIMF is a single-channel, 10-bit successive-approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a single power supply ranging from +2.7V to +5.25V and supports sample rates between 200 ksps and 500 ksps. The device features an internal track-and-hold circuit and outputs straight binary data via a high-speed serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 61.6 dB, Integral Non-Linearity (INL) of ±0.15 LSB, and Differential Non-Linearity (DNL) of ±0.15 LSB. Normal mode power consumption is 2.7 mW at 3.6V and 9.7 mW at 5.25V.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific package suffix against the datasheet to confirm physical dimensions and thermal characteristics. The CIMF designation corresponds to the SOT-23 package variant. Ensure that the ordering suffix matches the required lead-free status and environmental compliance standards defined by the manufacturer for production integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel conversion is required with moderate resolution and speed. The device is suitable for designs where the analog reference can be derived directly from the supply voltage. Consider the pin-compatible alternatives listed in Table 1 if different resolutions or higher sampling rates are needed without changing the PCB footprint.

Analog To Digital Converters (ADC) Part Context

The ADC101S051 belongs to a family of SAR ADCs that share pin compatibility across varying resolutions and speeds. Related parts include the ADC101S021 (50–200 ksps), ADC101S101 (500 ksps–1 Msps), and variants with 8-bit or 12-bit resolutions such as the ADC081S051 and ADC121S051. This allows designers to scale performance while maintaining board layout consistency.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible substitutes within the same family include the ADC101S021, ADC101S101, ADC081S051, and ADC121S051. These devices offer identical pinouts but differ in specified sample rate ranges and resolution. Verify that the alternative part meets the specific throughput and accuracy requirements of the application.

Analog To Digital Converters (ADC) FAQ

What is the maximum clock frequency supported by the ADC101S051?

The device supports a serial clock (SCLK) frequency range from 4 MHz to 10 MHz for specified electrical performance, though it remains functional up to 20 MHz.

How does the ADC101S051 handle power management?

It offers a power-down feature controlled by the CS pin. In shutdown mode (CS high), power consumption drops to approximately 2.6 µW at 5.25V, allowing significant energy savings in intermittent sampling applications.

What is the input voltage range for the analog signal?

The analog input voltage (VIN) must range from 0V to the positive supply voltage (VA). Exceeding these limits may activate internal ESD protection diodes and cause erratic operation.
