LTC1410IG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1410IG#PBF is a 12-bit, 1.25Msps sampling analog-to-digital converter (ADC) housed in a 28-lead plastic SSOP package. It operates from ±5V supplies with a full-scale input range of ±2.5V and dissipates 160mW during normal operation. The device features a differential sample-and-hold circuit with 20MHz bandwidth and 60dB common-mode rejection. Key performance metrics include ±1LSB integral nonlinearity, 71dB signal-to-(noise + distortion) ratio at Nyquist frequency, and no pipeline delay. Two digitally selectable shutdown modes provide Nap (7mW) and Sleep (10μW) power states.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the 'I' grade designation matches the required industrial operating temperature range of -40°C to +85°C. Ensure the SSOP package type aligns with the printed circuit board footprint design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range and low power consumption. The internal clock simplifies digital interface design by eliminating external synchronization requirements. Consider the 20MHz full power bandwidth for undersampling applications above the Nyquist frequency. Verify that the driving source impedance allows for the specified 100ns acquisition time.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1410 family of 12-bit SAR ADCs. The 'I' suffix denotes the industrial temperature grade variant, while 'G' specifies the 28-lead SSOP package. Other variants include the CSW package and C-grade commercial temperature options within the same functional family.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same package and pinout include the LTC1410CG#PBF for commercial temperature ranges or the LTC1410ISW#PBF if the SO Wide package is acceptable. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.

Analog To Digital Converters (ADC) FAQ

What is the maximum sampling frequency guaranteed for the LTC1410?

The maximum sampling frequency is 1.25MHz, corresponding to an 800ns throughput time.
