PRODUCTION DATA. PCM1860-Q1, PCM1861-Q1, PCM1862-Q1 PCM1863-Q1, PCM1864-Q1, PCM1865-Q1 SLASE64A – DECEMBER 2014 – REVISED JUNE 2017 PCM186x-Q1 Automotive, 4-Channel or 2-Channel, 192-kHz, Audio ADCs 1 1 Features 1 • AEC-Q100 Qualified for Automotive Applications – Temperature Grade 1: –40°C ≤ TA ≤ +125°C – HBM ESD Classification Level 2 – CDM ESD Classification Level C5 • High SNR Performance: – 110-dB SNR (PCM1861-Q1/63-Q1/65-Q1) – 103-dB SNR (PCM1860-Q1/62-Q1/64-Q1) • ADC Sample Rate (fS) = 8 kHz to 192 kHz • Up To Four Independent ADC Channels Available • Single-Ended, 2.1-VRMS Full-Scale (FS) Input • Differential, 4.2-VRMS FS Input • Hardware (HW) Control: PCM1860-Q1/61-Q1 • Software (SW) Control (I2C or SPI): PCM1862-Q1/63-Q1/64-Q1/65-Q1 • Support for Up To Four Digital Microphones (SW-Controlled Devices) • Programmable Gain Amplifier (PGA): – Fixed Gain: 0 dB, 12 dB, 32 dB (PCM1860-Q1/61-Q1) – SW-Controlled Gain: –12 dB to +32 dB (PCM1862-Q1/63-Q1/64-Q1/65-Q1) • Integrated High-Performance Audio PLL • Single 3.3-V Power-Supply Operation • Power Dissipation at 3.3 V: – < 85 mW (PCM1860-Q1/61-Q1/62-Q1/63-Q1) – < 145 mW (PCM1864-Q1/65-Q1) • Energysense Audio Content Detector for Auto System Wakeup and Sleep • Master or Slave Audio Interface • Automatic PGA Clipping Suppression Control • PCB-Footprint Compatibility Across All Devices 2 Applications • Automotive Head Units • External Car Amplifiers • Telematics Control Unit (TCU) 3 Description The PCM186x-Q1 family (PCM1860-Q1, PCM1861- Q1, PCM1862-Q1, PCM1863-Q1, PCM1864-Q1, and PCM1865-Q1) of audio front-end devices take a new approach to audio-function integration to ease compliance with European Ecodesign legislation, while enabling high-performance end products at reduced cost. The PCM186x-Q1 support single- supply operation at 3.3 V, and offer an integrated programable gain amplifier (PGA) in a small package; this configuration makes it feasible to implement smaller and smarter products at a reduced cost. The PCM186x-Q1 audio front end supports single- ended input levels from small-mV microphone inputs to 2.1-VRMS line inputs, without external resistor dividers. The front-end mixer (MIX), multiplexer (MUX), and PGA also support differential (Diff), pseudo-differential, and single-ended (SE) inputs, making these devices an ideal interface for products that require interference suppression. The PCM186x- Q1 integrate many system-level functions that assist or replace some DSP functions. An integrated band-gap voltage reference provides excellent PSRR, so that a dedicated analog 3.3-V rail may not be required.
