LTC1416CG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1416CG#PBF is a low-power, 14-bit sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates at a maximum sampling rate of 400ksps with a power dissipation of 70mW from ±5V supplies. The device features a high dynamic range sample-and-hold circuit and an internal precision reference. Key electrical specifications include a guaranteed –2LSB integral nonlinearity (INL) and –1.5LSB differential nonlinearity (DNL). It achieves an 80.5dB signal-to-(noise + distortion) ratio and 93dB total harmonic distortion at a 100kHz input frequency. The ADC utilizes a true differential input architecture to reject common-mode noise.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the 28-lead plastic SSOP specification. Confirm the temperature grade corresponds to the commercial range (0°C to 70°C) for the 'C' suffix. Ensure supply voltages are within the recommended operating conditions of VDD = 5V and VSS = -5V. Check datasheet requirements for bypass capacitors on AVDD, DVDD, and VSS pins to maintain stability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit resolution and 400ksps throughput are required with low power constraints. The internal reference simplifies design but can be overridden for higher accuracy. Consider the 15MHz full-power bandwidth if undersampling high-frequency signals. Verify that the microprocessor interface supports the parallel output and control signals like CONVST and BUSY.

Analog To Digital Converters (ADC) Part Context

The LTC1416 belongs to the LTC141x family of low-power sampling ADCs. It shares architectural similarities with the LTC1417 and LTC1418 but differs in interface type and sampling speed. The LTC1416 specifically offers a parallel digital output port, whereas other family members may utilize serial interfaces or different throughput rates. It is designed for applications requiring high dynamic range and low power consumption.
