ADS6144IRHBT

Analog To Digital Converters (ADC) Overview

The ADS6144IRHBT is a 14-bit, 105-MSPS analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a pipeline architecture and is housed in a VQFN-32 package. The device supports external or internal reference modes and features low power consumption with a typical power dissipation of 374 mW. Key performance metrics include an SFDR of 84 dB, an ENOB of 11.8 bits, and an SNR of 74.1 dB. Differential nonlinearity (DNL) is typically +/-0.6 LSB, while integral nonlinearity (INL) is typically +/-2.5 LSB. The input buffer is not included, and the analog input bandwidth is 500 MHz. It operates within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRHBT corresponds to the industrial temperature grade (-40°C to +85°C) and VQFN-32 package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability for critical applications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between high sampling speed (105 MSPS) and moderate resolution (14-bit) is required. Consider the absence of an input buffer if external buffering is feasible. Evaluate power constraints against the typical 374 mW dissipation. Compare against similar parts like ADS6142 or ADS6143 if channel count or speed requirements differ.

Analog To Digital Converters (ADC) Part Context

The ADS6144 belongs to the ADS61xx series of high-speed ADCs from Texas Instruments. This family targets applications needing fast conversion rates with good linearity. The IRHBT designation indicates the industrial temperature range and surface-mount packaging. It complements other devices in the portfolio such as the ADS6142 and ADS6143, which offer variations in pinout or feature sets.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS6142, ADS6143, and ADS6145. Verify pin compatibility and electrical specifications before substitution. Cross-reference datasheets to ensure equivalent performance in terms of SNR, SFDR, and power consumption.
