Analog Devices Inc. LT1213CS8#TRPBF

Overview

LT1213CS8#TRPBF from Analog Devices (formerly Linear Technology) is a dual, single-supply precision operational amplifier with 28MHz gain-bandwidth product, 12V/µs slew rate, and 275µV max input offset voltage at 25°C. It operates from 2.5V to 36V total supply, delivers ±30mA output drive, and supports rail-to-rail input (including ground) and near-rail output swing - ideal for 12-bit and 16-bit data acquisition systems.

For engineers reviewing the LT1213CS8#TRPBF datasheet, LT1213CS8#TRPBF pinout, LT1213CS8#TRPBF application, or LT1213CS8#TRPBF equivalent, this page provides verified package mapping (SO-8), confirmed DC precision specs across 3.3V/5V/±15V supplies, thermal resistance (θ_JA = 150°C/W), and real-world settling performance (500ns to 0.01% on 2V step).

Technical Context

The LT1213CS8#TRPBF uses a bipolar input stage enabling low input noise (10nV/√Hz) and high open-loop gain (≥1200 V/mV at ±15V), while maintaining stable phase margin (>45°) up to 28MHz. Its input common-mode range extends to ground and within 1.5V of V+, supporting true single-supply operation without level-shifting circuitry.

Output stage design allows sourcing up to 30mA while staying within 1.25V of V+ and sinking 30mA while rising only 690mV above V–, enabling direct interface with low-impedance loads such as DAC current-to-voltage converters and active filter feedback networks.

Key Specifications

Pinout & Package

LT1213CS8#TRPBF is housed in an 8-lead plastic SOIC (S8) package with standard JEDEC MS-012AC footprint, 1.27mm pitch, and exposed pad not present. Thermal resistance θ_JA = 150°C/W in still air.

FAQ

What is the maximum operating temperature range for the LT1213CS8#TRPBF?

The LT1213CS8#TRPBF is rated for operation from –40°C to +85°C ambient temperature. This grade is designated "C" in the part numbering scheme and is validated across that full range per the manufacturer's characterization data. The SO-8 package has a maximum junction temperature of 150°C, and thermal calculations must ensure TJ remains below this limit under worst-case power dissipation.

Does the LT1213CS8#TRPBF support true single-supply operation with input signals at ground potential?

Yes, the LT1213CS8#TRPBF supports true single-supply operation with inputs extending to the negative rail (ground). Its input common-mode range includes ground and reaches up to V+ – 1.5V at room temperature, enabling direct interfacing with sensors, switches, or DAC outputs referenced to ground without external level-shifting circuitry.

What is the guaranteed output drive capability of the LT1213CS8#TRPBF?

The LT1213CS8#TRPBF guarantees ±30mA minimum output current per amplifier, as confirmed in the datasheet's Electrical Characteristics tables under "Maximum Output Current" (IO) at ±15V, 5V, and 3.3V supplies. This drive strength is maintained across the full –40°C to +85°C temperature range and supports direct loading of 500Ω feedback networks or ADC reference buffers.

Can the LT1213CS8#TRPBF be used with a 3.3V supply, and what are its key performance metrics at that voltage?

Yes, the LT1213CS8#TRPBF is fully specified at 3.3V single supply. At 3.3V and 25°C, it delivers 275µV max input offset voltage, 2.7mA typical supply current per amplifier, 2.69V max output high swing (no load), and 0.007V max output low swing (no load). Settling time to 0.01% on a 2V step remains 500ns, confirming consistent dynamic performance across supply voltages.

Is the LT1213CS8#TRPBF pin-compatible with other dual op amps in SO-8 packages, such as the LT1013 or OP27?

No, the LT1213CS8#TRPBF is not pin-compatible with LT1013 or OP27. Its SO-8 pinout (OUT A, –IN A, +IN A, V–, V+, OUT B, –IN B, +IN B) differs from LT1013 (V–, OUT A, +IN A, –IN A, –IN B, +IN B, OUT B, V+) and OP27 (V–, OUT, +IN, –IN, NC, NC, NC, V+). Board redesign is required for substitution; always verify pin mapping before replacement.
