TLC320AD56CFN

Codecs Overview

The Texas Instruments TLC320AD56CFN is a single-supply analog interface circuit featuring a 16-bit resolution with a sampling frequency derived from the master clock divided by 512. It operates within a temperature range of 0°C to 70°C and utilizes a Quad Flat Package (FN) with 28 pins. The device supports a typical dynamic range of 85 dB for the DAC and 87 dB for the ADC, with minimum total signal-to-noise plus distortion ratios of 80 dB for the DAC and 79 dB for the ADC. Power consumption reaches a maximum of 150 mW in operating mode, dropping to a typical 2.5 mW in power-down mode.

Codecs Feature Summary

• Sigma-delta architecture providing high-resolution conversion through internal 64X oversampling
• Differential analog input and output design for enhanced common-mode rejection
• Integrated interpolation and decimation filters for efficient data rate management
• Configurable serial port interface supporting primary and secondary communication modes

Codecs Applications

• Business audio applications requiring low-speed signal conversion
• V.34 modem systems capable of supporting all standard sample rates
• General-purpose 16-bit digital signal processing environments

Codecs Procurement Notes

Verify the specific package variant against the datasheet before ordering, as the FN package denotes a Tape and Reel configuration while other suffixes may indicate different mechanical formats. Confirm that the required operating temperature range aligns with the commercial grade specifications provided in the official documentation. Ensure that the host system voltage levels are compatible with the TTL-compatible digital inputs and outputs defined for the device.

Codecs Selection Notes

Select this component when a differential sigma-delta codec with integrated filtering is required for low-power audio or data transmission. The device supports both single 5-V supply and mixed 5-V analog/3-V digital supply configurations. Consider the current-output nature of the DAC channel, which necessitates external resistive loading for proper voltage conversion. Verify that the available master clock frequency allows for the desired sampling rate calculation based on the MCLK/512 relationship.
