ADC101S101CISD

Analog To Digital Converters (ADC) Overview

The ADC101S101CISD is a single-channel, 10-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive-approximation register architecture with an internal track-and-hold circuit. The device supports sample rates from 500 ksps to 1 Msps and operates on a single supply voltage ranging from +2.7V to +5.25V. Key electrical specifications include a typical signal-to-noise ratio (SNR) of 62 dB, integral non-linearity (INL) of ±0.2 LSB, and differential non-linearity (DNL) of +0.3/-0.2 LSB. Power consumption is 2.0 mW at +3V and 10 mW at +5V in normal mode, reducing to 2.5 µW in shutdown mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package suffix 'SD' corresponds to the specific 6-lead WSON or SOT-23 variant required for the design. Confirm that the ordering suffix does not alter the functional specifications unless explicitly stated in the manufacturer's documentation. Ensure compatibility with the intended serial interface protocol before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 10-bit resolution is required with throughput up to 1 Msps. It is suitable for applications needing compatibility with standard microprocessor serial buses. Consider the thermal resistance of the chosen package (94°C/W for WSON, 265°C/W for SOT-23) when designing for high ambient temperatures.

Analog To Digital Converters (ADC) Part Context

The ADC101S101 belongs to a family of pin-compatible converters offering different resolutions and speeds. Alternatives include the ADC121S101 (12-bit), ADC101S051 (10-bit, 500 ksps max), and ADC081S101 (8-bit). All devices in this series share identical pinouts and functionality, allowing for easy upgrades or downgrades in resolution without PCB redesign.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include ADC121S101, ADC101S051, and ADC081S101. These parts maintain the same footprint and interface but differ in resolution or maximum sample rate. Verify that the alternative meets the specific dynamic performance requirements of the application.

Analog To Digital Converters (ADC) FAQ

What is the input voltage range for the ADC101S101?

The analog input voltage (VIN) ranges from 0V to VA, where VA is the positive supply voltage connected to the device.

How many clock cycles are required to read a complete conversion result?

Sixteen SCLK cycles are required to read a complete sample. The output consists of three leading zero bits, ten data bits, and two trailing zero bits.

What is the minimum quiet time required between conversions?

A minimum quiet time (tQUIET) of 50 ns is required after the SDATA pin returns to TRI-STATE before CS can be pulled low to initiate the next conversion.
