| Systemcom Launches New Analog Front-End IP with 13-bit ADC at TSMC 180nm | | |
July 16, 2012 -- Systemcom, Ltd. has expanded it available IP (intellectual property) module and ASIC/ ASSP product line. The latest analog front-end for current measurement with 13-bit ADC is ready to be embedded into an SOC with sensors/ MEMS at its input. It is also available as ASIC/ ASSP solution. This AFE at 180nm satisfies the needs systems with high requirements in terms of high linearity, low power consumption (ideally for battery powered devices), wide input-current range and extended industrial-temperature range.
SC-I-AFE-180F110 key benefits
-
Detection and measurement of low input-current values in the range of hundreds of picoA to 1 mA (up to 90dB dynamic range) and measurement of current difference down to the level of tens of picoA.
-
High sensitivity of the measurement thanks to wide range of current-to-voltage conversion ratios together with PGA (overall gain up to 1296). Analog signal processing enables high-gain amplification while keeping the highest resolution.
-
Current-to-voltage conversion features high linearity: < 0.5LSB per gain stage for 13-bit resolution, achieved by TIA architecture.
-
Embedded highly linear, low-power 13-bit ADC with programmable resolution and programmable sampling rate, suitable for AFE applications with various sensor types regarding speed and sensitivity requirements.
-
Built-in standard SPI interface for digital communication and incorporated FIFO buffer for ADC.
-
Chip operates at supply voltages from 1.6V to 1.8V in the temperature range from -40°C to 125°C. Reference voltages, bandgap and current references are internally embedded.

This AFE is designed in TSMC 180-nm technology but it can be easily migrated towards other foundries and processes. The product development strategy includes a wide choice of customization for application specifics: customizable current ranges, rearrangement of the PGA gain, etc. It is ideally suited for photo sensing, especially useful in biomedical equipment where optical and electrochemical sensors are mostly used (e.g., blood analysis devices, oxygen sensors, CO sensors, etc.)
Availability
SC-I-AFE-180F110 is available now.
