Product details
Overview
AD74111YRU-REEL7 from Analog Devices is a 2.5 V mono audio codec IC featuring integrated 24-bit sigma-delta ADC and DAC channels, programmable 0–12 dB PGA gain, software-controllable clickless mute, and on-chip 1.125 V reference. It supports 8–48 kHz sample rates, 16/20/24-bit word lengths, and operates across –40°C to +105°C for automotive-grade voice and audio front-end applications.
For engineers reviewing the AD74111YRU-REEL7 datasheet, AD74111YRU-REEL7 pinout, AD74111YRU-REEL7 application, or AD74111YRU-REEL7 equivalent, key selection considerations include its TSSOP-16 package, 3.3 V-tolerant digital interface, low group delay mode (87 µs ADC / 55 µs DAC), 85 dB ADC dynamic range, and 93 dB DAC dynamic range - all critical for telematics, portable audio, and DVC signal chain design.
Technical Context
The AD74111YRU-REEL7 implements multibit sigma-delta modulation in both ADC and DAC paths, with oversampling ratios of 64× (ADC) and 128× (DAC), decimation/interpolation filtering, and selectable low-group-delay operation. Its serial port supports master/slave configuration via DIN state at reset and accommodates 16-/20-/24-bit data formats in mixed or data modes.
It uses three independent power domains: AVDD (2.5 V analog), DVDD2 (2.5 V core digital), and DVDD1 (2.5–3.3 V I/O-tolerant digital), with PSRR >72 dB at 1 kHz and 50/60 Hz. Internal MCLK prescalers (/1–/3, /1–/3, /1–/4) enable flexible sample rate derivation from a single external clock (e.g., 12.288 MHz → 48 kHz or 8 kHz).

FAQ
What is the operating temperature range specified for the AD74111YRU-REEL7?
The AD74111YRU-REEL7 is rated for –40°C to +105°C, matching the automotive temperature grade (Y version). This specification is guaranteed per the Ordering Guide and Absolute Maximum Ratings table, and applies to all electrical parameters including dynamic range, THD+N, and power supply rejection ratio across the full range.
Does the AD74111YRU-REEL7 support external reference voltage?
Yes, the AD74111YRU-REEL7 supports external reference voltage via the REFCAP pin. Control Register A allows disabling the internal 1.125 V reference, after which an externally supplied reference can be applied to REFCAP. The external reference must be adequately decoupled and maintain proper headroom relative to AVDD and DVDD supplies.
How does the AD74111YRU-REEL7 achieve low group delay, and what is the minimum achievable value?
The AD74111YRU-REEL7 achieves low group delay by enabling the Low Group Delay function in Control Register C, which bypasses portions of the on-chip digital filtering. At 48 kHz, this reduces ADC group delay from 910 µs to 87 µs and DAC group delay from 505 µs to 55 µs - critical for real-time voice feedback and echo cancellation.
What are the supported serial interface modes for the AD74111YRU-REEL7?
The AD74111YRU-REEL7 supports Mixed Mode (control register access + audio data transfer) and Data Mode (audio-only), each configurable for 16-/20-/24-bit word length and Normal/Fast timing. Master or Slave operation is selected by the DIN pin state at reset, and Multiframe-Sync mode is available for deterministic DSP synchronization.
Can the AD74111YRU-REEL7 operate with different supply voltages on DVDD1 and DVDD2?
Yes - DVDD1 is specified for 2.375 V to 3.6 V to accommodate 3.3 V-tolerant digital interfaces, while DVDD2 is strictly 2.375 V to 2.625 V for the 2.5 V digital core. This separation allows interfacing with 3.3 V controllers without compromising core logic integrity or increasing noise coupling into the analog section.
