Texas Instruments AMC1305M05EVM

Overview

AMC1305M05EVM from Texas Instruments is a dedicated evaluation module for the AMC1305M05 isolated delta-sigma modulator, supporting rapid prototyping of high-accuracy current sensing in industrial motor drives and power converters. It features screw-terminal analog inputs (±50 mV range), CMOS digital interface, 1 MHz input bandwidth, onboard isolated power generation via SN6501 and DA2304 transformer, and compatibility with TMS320F28377D or AMC1210 digital filters.

For engineers reviewing the AMC1305M05EVM datasheet, AMC1305M05EVM pinout, AMC1305M05EVM application, or AMC1305M05EVM equivalent, this page delivers verified hardware configuration details, isolation architecture context, modulator interface timing constraints, and real-world setup guidance for precision analog-to-digital conversion validation.

Technical Context

The AMC1305M05EVM implements a capacitive-isolated, second-order switched-capacitor ΔΣ modulator evaluation platform with galvanic isolation up to 7000 V_PEAK. Its analog front-end includes RC filtering at J2, while digital interface uses CMOS-level DOUT/CLKIN signals routed to screw terminals J3 and J4.

Power architecture supports dual supply modes: external high-side rail (via J5, JP1=Ext) or controller-side-derived isolated supply (via J1 → SN6501 → DA2304 → MBR0520L → TLV70450). The onboard LDO ensures stable 5.0 V AVDD for the AMC1305M05 under varying load conditions.

FAQ

What is the primary function of the AMC1305M05EVM?

The AMC1305M05EVM is an evaluation module built exclusively to prototype and validate the AMC1305M05 isolated delta-sigma modulator. It provides direct access to the device's ±50 mV analog inputs, CMOS digital outputs, and isolated power supply chain - enabling engineers to verify performance in real-time current sensing applications before committing to custom PCB design. The AMC1305M05EVM does not operate as a standalone measurement instrument but serves as a hardware reference for system integration.

Does the AMC1305M05EVM include the AMC1305M05 device?

Yes, the AMC1305M05EVM is shipped populated with the AMC1305M05 device in a 16-pin SOIC (DW) package. Table 2 of the SBAU237 user's guide explicitly lists U1 as "AMC1305M05" with quantity "1" under the "M05" column. No additional modulator IC purchase is required to begin evaluation - the AMC1305M05 is soldered and tested on the board prior to shipment.

Can the AMC1305M05EVM generate isolated power without an external high-side supply?

Yes. When jumper JP1 is set to the "Iso" position, the AMC1305M05EVM derives isolated AVDD using the onboard SN6501 driver, DA2304 transformer, MBR0520L rectifier, and TLV70450 LDO - all powered solely from the controller-side supply applied to J1 (3–5.5 V DC). This eliminates the need for a separate high-voltage rail and allows full functional evaluation of the AMC1305M05 using only one low-voltage source.

What digital filter devices are compatible with the AMC1305M05EVM output?

The AMC1305M05EVM is explicitly validated with the ΔΣ filter module inside the TMS320F28377D C2000 MCU and the standalone AMC1210 digital filter IC, as documented in Section 1.2 and Section 3 of the SBAU237 user's guide. Both accept the CMOS-format bitstream from the AMC1305M05 and reconstruct 16-bit resolution data at 78 kSPS with 80 dB dynamic range (13 ENOB).

Is the AMC1305M05EVM rated for high-voltage isolation testing?

No. The AMC1305M05EVM is strictly intended for electrical characterization of the AMC1305M05 modulator under lab conditions - not for safety-critical isolation validation. As stated in Section 5.1, "The EVM is not meant for isolation tests and is not designed to be used in a high-voltage environment." Its transformer (DA2304) and layout do not meet the creepage/clearance or dielectric test requirements needed for certification-grade isolation verification.
