Samsung TVs output audio digitally through an optical (Toslink) or coaxial port, but plenty of older speakers, soundbars, and stereo receivers only accept analog RCA or a 3.5mm input. A digital-to-analog converter bridges that gap cheaply. Here’s the real range, from the sub-$20 basics to step-up options worth it if you’re feeding a proper stereo amp rather than a pair of powered speakers.

The picks, in detail
1Mii Digital to Analog Audio Converter
A compact, well-reviewed budget converter that handles both optical and coaxial digital input, outputting to RCA and a 3.5mm jack simultaneously.
- Optical (Toslink) and coaxial digital inputs
- Simultaneous RCA L/R and 3.5mm outputs
- Supports 32-192kHz sample rates
- Includes optical cable
- Very cheap and does exactly one job reliably
- Handles two digital input types, useful if the TV changes output format
- Basic internal DAC — fine for TV dialogue/soundtrack, not for critical music listening
FiiO D03K Taishan
A well-regarded budget DAC from an established audio brand, a step up in build and sound quality from the true budget converters at a similar price.
- Optical and coaxial digital inputs
- RCA analog output
- Supports up to 24-bit/192kHz

- Compact, no-driver plug-and-play setup
- Purpose-marketed for exactly this TV-to-analog scenario
- Simple setup with no software or drivers
- Basic DAC quality suited to TV audio, not audiophile use
PROZOR 192kHz Digital to Analog Audio Converter
One of the most commonly recommended budget picks specifically for Samsung TV optical-to-RCA conversion, per current buyer’s guides.
- Toslink and coaxial digital inputs
- RCA and 3.5mm analog outputs

- Build quality is basic plastic, matching the low price
Camway Digital to Analog Audio Converter
A versatile budget converter supporting a wide sample-rate range with a built-in amplifier chip to strengthen the RCA output signal.
- 32/44.1/48/96/192kHz sample rate support
- 24-bit stereo output
- Built-in amp chip to boost RCA signal strength
- Toslink and coaxial inputs
- Amplified RCA output can help with weaker analog speaker setups

UGREEN Optical to RCA Converter
A reliable, widely-stocked option from a well-known cable/accessory brand — a safe, no-surprises budget pick with strong retail availability.
- Toslink optical input
- RCA L/R analog output
- Compact aluminum housing
- USB power cable included
- Strong brand reliability and easy returns/support through major retailers
- Solid build quality for the price tier
- Optical input only, no coaxial option on this model
Topping D10s
A genuine step-up option for anyone feeding a real stereo amplifier rather than powered speakers — a proper desktop DAC with optical/coaxial digital input and RCA line-level output.
- Optical, coaxial, and USB digital inputs
- RCA analog line-out
- Supports up to 32-bit/768kHz over USB, 24-bit/192kHz optical/coax
- AK4493 DAC chip
- Meaningfully better sound quality than the sub-$25 converters
- Doubles as a USB DAC for a connected PC, not just the TV
- Priced well above the basic TV-converter tier — overkill if you’re just feeding a soundbar
SMSL SU-1
Another budget-audiophile DAC brand’s entry-level desktop unit, comparable to the Topping D10s for buyers who want real fidelity from their TV’s digital audio.
- Optical, coaxial, and USB digital inputs
- RCA analog output
- ES9018K2M DAC chip
- Compact desktop enclosure
- Strong measured audio performance for the price versus true budget converters
- Reputable brand in the budget-audiophile DAC space
- Same overkill caveat as the Topping — only worth it if sound quality into real speakers matters to you
Buying tips
- Check your Samsung TV’s audio output settings first — set it to stereo PCM rather than a compressed multichannel format (Dolby Digital passthrough won’t decode correctly through a basic 2-channel converter).
- If your TV only has one digital output type, confirm it matches the converter’s input — most Samsung sets use optical (Toslink), but some also expose coaxial.
- The sub-$25 converters here are all functionally similar and fine for TV dialogue and soundtrack; only step up to the Topping/SMSL tier if you’re driving a proper stereo amp where sound quality is actually noticeable.
- These converters only pass 2-channel stereo — if you need full surround sound from a soundbar/receiver, you need HDMI ARC/eARC or a receiver with a digital input, not a simple DAC like these.
