Description for the PCM1870

The PCM1870 is a low-power stereo ADC designed for portable digital audio applications, with line-input amplifier, boost amplifier, microphone bias, programmable gain control, sound effects, and auto level control (ALC). It is available in 24-QFN (4-mm × 5-mm) and 24-DSBGA (2.49-mm × 3.49-mm) packages to save footprint. The PCM1870 accepts right-justified, left-justified, I2S, and DSP formats, providing easy interfacing to audio DSP and encoder chips. Sampling rates up to 50 kHz are supported. The user-programmable functions are accessible through a 2- or 3-wire serial control port.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
