The PCM1602A and PCM1609A are cost-effective, high-performance,
multilevel delta-sigma digital-to-analog converters. These 6-channel
(PCM1602A) and 8-channel (PCM1609A) audio DACs utilize TI’s
enhanced multilevel delta-sigma architecture to achieve excellent
dynamic performance and improved tolerance to clock jitter.

The TS3A5018 is a quad, single-pole, double-throw (SPDT) analog
switch designed to operate from 2.3 V to 3.6 V. This device can handle
both digital and analog signals, and signals up to V+ can be transmit-
ted in either direction.
Key Features
• Low on-state resistance (7-Ω typ)
• Low charge injection (2 pC)
• Excellent on-state resistance matching
• Low total harmonic distortion or THD (0.2%)
• 2.3- to 3.6-V single-supply operation
• Control inputs are 5-V tolerant
Applications
• Sample-and-hold circuit
• Battery-powered equipment
• Audio and video signal routing
• Communication circuits
