THS1230IPWR

Analog To Digital Converters (ADC) Overview

The THS1230IPWR is a 12-bit, 30 MSPS analog-to-digital converter (ADC) from Texas Instruments, housed in a 28-pin TSSOP (PW) package. It operates on a single 3.3-V supply and features a differential analog input with configurable gains of 0.5x or 1.0x via CON0 and CON1 pins. The device includes an internal voltage reference, an out-of-range indicator, and a power-down mode for reduced consumption. Electrical characteristics specify a typical DNL of ±0.4 LSB and INL of ±1.2 LSB at 30 MHz sampling. It supports industrial temperature ranges (-40°C to 85°C) and utilizes a pipeline architecture with a 5-cycle latency.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IPWR' corresponds to the tape-and-reel packaging variant with 2000 units per reel. Confirm the 'I' grade indicates the extended industrial temperature range of -40°C to 85°C. Ensure compatibility with the 28-pin TSSOP footprint during PCB layout. Check for RoHS compliance status as indicated by the G4 suffix variants if lead-free specifications are required.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-speed, low-power 12-bit conversion is required for video or communications signals. The differential input configuration simplifies interface design for balanced sources. Consider the 5-cycle pipeline latency when designing clock synchronization logic. Verify that the source impedance meets the requirements for settling within half a clock cycle at the target sampling frequency.

Analog To Digital Converters (ADC) Part Context

The THS1230 series comprises CMOS ADCs designed for 3.3-V applications. The IPWR designation specifically identifies the industrial temperature grade version packaged in a tape-and-reel format suitable for automated surface-mount assembly. Other variants include the CDW/C PW for commercial temperatures and DW packages for different physical footprints.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include THS1230IPW (tube packaging) and THS1230CPWR (commercial temperature). Cross-family comparisons should account for differences in resolution, sampling speed, and input architecture.
