SSP3485
The SSP3485 is a half-duplex high speed transceiver for RS-485 and RS422 communication. IC contains one driver and one receiver.
The SSP3485 has a fail-safe circuit. It has a slew-rate-limited driver that reduces EMI and reflection due to improperly matched terminal cables, and achieves error-free data transmission of up to 10Mbps. Each driver output and receiver input is protected against ±15kV electrostatic discharge (HBM) (ESD)shocks.
The SSP3485 receiver has 1/8 unit load input impedance, allows up to 256 devices can be attached to the bus. Mainly used in RS-485/RS-422 communication system.
SSP3085
The SSP3085 is a half-duplex high speed transceiver for RS-485 and RS422 communication. IC contains one driver and one receiver.
The SSP3085 has a fail-safe circuit, ensure logical high level of receiver output when receiver input is open or short. It can achieve error-free data transmission of up to 500kbps. Each driver output and receiver input is protected against ±15kV electrostatic discharge (HBM) (ESD)shocks.
The SSP3085 receiver has 1/8 unit load input impedance, allows up to 256 devices can be attached to the bus.
SSP721A
SSP721A is a single chip transceiver developed for Meter-Bus standard (EN1434-3、EN13757) applications.
The SSP721A interface circuit adjusts the different potentials between a slave system and the Meter-Bus master. The connection to the bus is polarity independent and supports full galvanic slave isolation with optocouplers. The circuit is supplied by the master via the bus. Therefore, this circuit offers no additional load for the slave battery. A power-fail function is integrated. The receiver has dynamic level recognition, and the transmitter has a programmable current sink. A 3.3V voltage regulator, with power reserve for a delayed switch off at bus fault, is integrated.
SSP1120
The SSP1120 is a precision, 16-bit, analog-to-digital converter (ADC) that offers many integrated features to reduce system cost and component count in applications measuring small sensor signals.
The device can perform conversions at data rates up to 2000 samples-per-second (SPS) with single-cycle settling. At 20 SPS, the digital filter offers simultaneous 50-Hz and 60-Hz rejection for noisy industrial applications. The internal PGA offers gains up to 128 V/V. This PGA makes the SSP1120 ideally suited for applications measuring small sensor signals, such as resistance temperature detectors (RTDs), thermocouples, thermistors, and bridge sensors.
Power consumption is as low as 120 µA@3.3V when operating in duty-cycle mode with the PGA disabled.
The SSP1120 is offered in a TSSOP-16 package and is specified over a temperature range of –40°C to +125°C.
