It operates from a single 5 V VCC supply, complies with the ISO 11898 standard, and supports high-speed data rates up to 1 Mbps. The device is offered in an 8-lead SOIC package and is supplied in tape-and-reel packaging for high-volume assembly. What is a CAN transceiver? A controller area network (CAN) transceiver is an interface IC that converts logic-level signals from a CAN controller into the differential signals required on the CANH and CANL bus lines, and vice versa. It sits between the protocol controller and the physical twisted-pair bus, providing the required differential drive, receive sensitivity, and protection functions. In the system hierarchy, a CAN transceiver is part of the physical layer in a CAN network, below the data-link and application layers. The ADM3051 is a non-isolated, single-channel half-duplex transceiver intended for industrial and automotive networks where ISO 11898 compliant communication at up to 1 Mbps is required. Key features of ADM3051BRWZ-RL7 include short-circuit protection on CANH and CANL for shorts to power or ground in 24 V systems, operation with unpowered nodes that do not disturb the bus, and capability to connect 110 or more nodes. It also provides slope control on the RS pin to reduce radiated EMI, thermal shutdown protection, and a low-current standby mode for power-sensitive applications. These features make it a physically robust PHY for noisy or high-node-count environments. Technically, the ADM3051 is a CAN physical-layer IC in the Analog Devices ADM305x family. It uses a differential bus interface and includes bus fault protection and thermal shutdown in a single 8-pin SOIC package. The -RL7 suffix denotes 7-inch reel tape-and-reel packaging, and the BRWZ code indicates the lead-free (Z) SOIC (RW) package variant. The device is designed for 5 V-only systems, simplifying power supply design and enabling direct interface to 5 V CAN controllers without extra level shifting. Typical applications include industrial automation PLCs, automotive body electronic modules, building management system controllers, battery management systems, medical equipment and CAN data logging nodes. In each of these, the ADM3051's 1 Mbps speed, 110+ node bus capability, and short-circuit protection reduce risk of fieldbus faults while maintaining simple 5 V power architecture. When designing with ADM3051BRWZ-RL7, place a 120 ohm termination resistor between CANH and CANL at both ends of the bus and set the RS pin resistor to control the slew rate for EMI optimization. For best decoupling, use a 100 nF ceramic capacitor close to VCC and a bulk capacitor at the supply point.
ADM3052BRWZ-RL7 - Isolated CAN Transceiver 5kV | ADI
The Analog Devices ADM3052BRWZ-RL7 is an isolated Controller Area Network (CAN) physical layer transceiver with an integrated linear regulator, supplied in a 16-lead SOIC (SOIC-W) package on 7-inch tape and reel. It complies with ISO 11898 and uses Analog Devices iCoupler technology to combine a 3-channel digital isolator and a CAN transceiver in one package. The device supports data rates up to 1 Mbps and provides 5 kVrms signal isolation. An isolated CAN transceiver is an interface IC that places a galvanic isolation barrier between the logic-side CAN controller and the physical bus-side transceiver. In a CAN node, the controller sends TXD/RXD signals across the isolation barrier to the transceiver, which then drives the differential CANH and CANL bus lines. This prevents ground loops, common-mode voltages, and transient noise in industrial or automotive networks from disturbing the local microcontroller. The transceiver sits in the signal chain between the CAN controller and the twisted-pair bus, making isolation a key reliability requirement in harsh environments. Key features of the ADM3052 family include 5 kVrms isolation voltage, a 1/1 driver/receiver configuration, 1 Mbps ISO 11898-compliant data rate, and a logic-side supply of 3.3 V or 5 V. The integrated linear regulator enables bus-powered operation from a 24 V-class V+ rail, eliminating the need for a separate isolated DC-DC converter in many nodes. The 16-lead SOIC wide-body package supports surface-mount assembly and automated tape-and-reel production. From a design perspective, the ADM3052 integrates the isolation barrier, CAN transceiver, and LDO regulation into one package, simplifying PCB layout and reducing component count. The iCoupler technology provides common-mode transient immunity that is critical for reliable CAN communication in motor drives, battery packs, and factory-floor networks. Because the bus side can be powered directly from V+, the node can be designed as a two-wire bus-powered device in applications where a standalone isolated supply is not economically justified. Typical applications include automotive electronic control units, battery management systems, industrial CANopen networks, building automation, medical monitoring equipment, and test instrumentation. The combination of 5 kVrms isolation and bus-powered regulation makes the ADM3052 especially useful in distributed sensor nodes that must survive ground potential differences. When designing with this device, pay attention to the input voltage range and dropout of the integrated linear regulator, and place adequate bypass capacitance on the V+ and logic-side rails. The isolation barrier also requires proper PCB creepage and clearance to maintain the specified 5 kVrms withstand voltage.

Key features include single-supply 3.3 V operation with an on-chip charge pump voltage doubler/inverter, conformance to EIA-232E and V.28 specifications, high-speed operation up to 460 kbps, and small 0.1 uF external charge pump capacitors that reduce board area and bill-of-materials cost compared to older parts requiring 1 uF or larger capacitors. Technically, the ADM3202 integrates two charge pump stages (doubler and inverter) to generate approximately +/-6 V RS-232 rails from the 3.3 V supply. The drivers deliver guaranteed EIA-232E output levels, and the receivers include internal input pull-ups so that unconnected receiver inputs default to a known mark state. The ADM3202 variant has no shutdown pin; the related ADM3222 and ADM1385 add a low-power shutdown facility for battery applications. Typical applications include industrial equipment serial ports, embedded systems with RS-232 debug or console links, point-of-sale terminals, battery-powered portable instrumentation (with ADM3222 variants), and any 3.3 V microcontroller design interfacing to legacy RS-232 equipment. Design considerations: place the four 0.1 uF charge pump capacitors as close as possible to the device pins and observe datasheet polarity for the flying capacitors; ensure the supply can support the transient charge pump current during data transmission.

An RS-232 transceiver is an interface IC that converts logic-level UART signals (TTL/CMOS, typically 0 V to 3.3 V) to the higher voltage swings defined by the EIA-232E and ITU V.28 standards, and vice versa. Within the signal-chain hierarchy, it belongs to the interface IC family alongside RS-485, CAN and USB transceivers, and sits between a microcontroller UART and a physical D-sub serial port. Because RS-232 rails can swing to +/-5 V or more, an integrated charge pump (voltage doubler and inverter) is required when only a single low-voltage supply is available. Key features of the ADM3202 include guaranteed 460 kbps operation for high-speed serial links, operation from a 3 V to 5.5 V supply range per distributor parametric data, EIA-232E/V.28 conformance, and a small external capacitor requirement of only 4 x 0.1 uF, which reduces board area and BOM cost. The complementary ADM3222/ADM1385 family members add a low-power shutdown facility for battery-powered portable instruments. Technically, the device uses CMOS charge-pump technology with integrated driver and receiver channels. The charge doubler generates V+ and the inverter generates V- from the 3.3 V rail, enabling true RS-232 output levels without a dual supply. Receivers incorporate hysteresis and tolerate input voltages up to +/-30 V, improving noise immunity on long cables. Typical applications include industrial point-of-sale equipment, networking and communication equipment serial management ports, embedded systems console/debug ports, and battery-powered portable instruments with RS-232 connectivity. Design considerations: place the four 0.1 uF charge pump capacitors as close as possible to pins 1-6, and use at least 0.1 uF of supply decoupling on VCC; note the ADM3202 itself lacks the shutdown pin available on the ADM3222 variant.
