Relmon Technology introduces the MS5179: a 16-channel, 12-bit successive-approximation ADC with a maximum throughput rate of 1 MSPS, support for configurable channel sequences, and a SINAD of ≥68 dB at 50 kHz input – delivering a cost-effective solution for multi-channel data acquisition.
Key Advantages
-
16-Channel Single-Ended Input with Configurable Sequence
Supports 16 single-ended analog inputs. The conversion sequence can be preset via the control register, flexibly adapting to different numbers of active channels in the system.
-
1 MSPS High-Speed Throughput with No Pipeline Delay
Delivers up to 1 MSPS throughput with zero pipeline latency, ensuring every conversion result is valid in real time – ideal for high-speed multi-channel acquisition systems.
-
High SINAD: ≥68 dB at 50 kHz
Achieves ≥68 dB SINAD at 50 kHz input, enabling accurate recovery of weak signals.
-
6.4 mW Operating Power, 0.5 μA Shutdown Current
Consumes only 6.4 mW at 3 V supply and 1 MSPS; supports multiple power modes, with shutdown current as low as 0.5 μA, offering flexible trade-offs between performance and energy consumption.
-
Flexible Input Range and Output Coding
Configurable input voltage range (0 V to VREFIN or 0 V to 2×VREFIN), and selectable standard binary or two’s complement output to match various front-end signals and processor interfaces.

Application Scenarios
EDFA (Erbium-Doped Fiber Amplifier)
In EDFA systems, multiple analog signals – such as pump laser power, input/output optical power, and temperature – must be monitored simultaneously for closed-loop control. The MS5179’s 16-channel input can acquire all monitoring points in a single conversion cycle, while 1 MSPS high-speed sampling tracks power fluctuations in real time. Its 12-bit resolution combined with 68 dB SINAD ensures accurate optical power monitoring, providing precise data support for EDFA gain control and system protection.
Multi-Channel Data Acquisition Systems
Industrial automation, test and measurement, and other systems often require simultaneous monitoring of multiple analog channels. The MS5179 supports configurable channel sequences, and its multiple power management modes allow automatic power reduction during low-throughput operation, making it well-suited for battery-powered portable devices.
With its 16-channel input, 1 MSPS high-speed sampling, 6.4 mW low power consumption, and 68 dB high SINAD, the MS5179 offers a high-cost-performance ADC solution for EDFA and multi-channel data acquisition applications.
