STMicroelectronics L272D013TR

Overview

L272D013TR from STMicroelectronics is a dual high-output-current power operational amplifier in SO16 narrow package, delivering 1 A continuous output current per channel, operating from single or split supplies up to ±14 V (28 V total), with ground-compatible inputs and thermal shutdown at 145 °C - used in bidirectional DC motor control, CD servo systems, and capstan motor drivers.

For engineers reviewing the L272D013TR datasheet, L272D013TR pinout, L272D013TR application, or L272D013TR equivalent, key selection criteria include output current capability (1 A), slew rate (1 V/µs), gain-bandwidth product (350 kHz), thermal shutdown threshold (145 °C), and SO16 narrow package compatibility with compact disc and VCR power-stage designs.

Technical Context

The L272D013TR integrates two independent high-power op-amps on a single die, each featuring rail-to-rail input stage with common-mode range extending to ground, and Class AB output stage enabling low saturation voltage (≤2.5 V at 0.5 A) under heavy load. Its internal thermal shutdown circuit activates at 145 °C junction temperature.

It supports both single-supply (4–28 V) and split-supply (±2–±14 V) operation, with input offset voltage ≤60 mV and open-loop gain ≥50 dB at 1 kHz. Channel separation is ≥60 dB at 1 kHz with 10 Ω load, confirming suitability for dual-channel precision power amplification.

FAQ

What is the maximum safe continuous output current per channel for L272D013TR?

The L272D013TR delivers 1 A DC output current per channel continuously under specified thermal conditions (T_case ≤ 90 °C). At ambient temperatures above 50 °C without heatsinking, derating applies per the 100 °C/W R_{th j-amb} value - sustained 1 A operation requires PCB copper area or external heatsink to maintain junction temperature below 145 °C.

Can L272D013TR operate from a single 5 V supply?

Yes - the L272D013TR operates from single supplies as low as 4 V. With 5 V supply, its output swing reaches ≥3.5 V at 100 mA load, and inputs accept signals down to ground. However, slew rate and GBW decrease slightly at lower voltages; verify stability with 100 nF supply decoupling and avoid capacitive loads >100 pF without isolation resistor.

Does L272D013TR have built-in ESD protection on input pins?

The L272D013TR does not specify human-body-model (HBM) ESD rating in the July 2003 datasheet. It includes basic junction protection but lacks dedicated input clamp diodes or high-impedance ESD structures. External 10 kΩ series resistors and 100 pF shunt capacitors are recommended for I/O lines exposed to handling or connector interfaces.

Is L272D013TR pin-compatible with L272M or L272 in Powerdip packages?

No - L272D013TR (SO16 narrow) has different pin mapping than L272M (Minidip) and L272 (Powerdip). While all share identical electrical functionality and pin function definitions, physical pinouts differ: SO16 uses 1–8 and 9–16 for dual channels, whereas Powerdip places outputs on pins 1/10 and 8/15. PCB layout and footprint must be redesigned for package interchange.
