LTC1276ACN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1276ACN#PBF is a 12-bit, 300ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It features an internal voltage reference and supports differential or single-ended inputs via a parallel interface. The device operates on a single 5V supply with a typical power dissipation of 75mW. Key performance metrics include a differential nonlinearity (DNL) of 0.75 LSB, integral nonlinearity (INL) of 0.5 LSB, and a signal-to-noise and distortion ratio (SINAD) of 70 dB. It is housed in a 24-lead PDIP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status before procurement. Confirm the PDIP-24 package availability as distribution channels may vary. Ensure the operating temperature range of 0°C to +70°C aligns with the target application environment requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring moderate speed and high accuracy without external reference components. Compare against the LTC1274 if a lower 100ksps sample rate is sufficient, or consider the MAX1276 family if a serial SPI interface is preferred over the parallel interface provided here.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1276 series of 12-bit ADCs from Linear Technology (now Analog Devices). It shares architectural similarities with the LTC1274 but offers a higher sampling rate of 300ksps compared to the 100ksps of the LTC1274. Both devices utilize SAR architecture and internal references.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1276 is a functional alternative from Maxim Integrated offering similar 12-bit resolution but utilizes a serial interface instead of parallel. For direct pin-compatible replacement within the same manufacturer's portfolio, verify specific electrical parameter overlaps with other LTC12xx series parts.
