Product details
Overview
TCM2913J from Rochester Electronics is a dual-channel, low-power, rail-to-rail operational amplifier with 1.2 MHz gain-bandwidth product, 0.8 V/µs slew rate, and ±1.5 V to ±16 V supply voltage range; used in precision sensor signal conditioning and portable instrumentation front-ends.
For engineers reviewing the TCM2913J datasheet, TCM2913J pinout, TCM2913J application, or TCM2913J equivalent, key selection factors include input offset voltage (±1.5 mV max), CMRR (80 dB min), and guaranteed operation over –40°C to +85°C industrial temperature range.
Technical Context
The TCM2913J integrates two independent op-amps in a single SOIC-8 package with internal ESD protection and unity-gain stable design. It features input bias current of 50 pA max and output short-circuit protection.
Designed for DC-coupled and low-frequency AC applications, the TCM2913J supports single-supply operation down to 3 V and delivers 100 dB open-loop gain at 1 kHz, enabling high-accuracy amplification without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.2 MHz - supports stable closed-loop gain up to 100 at 12 kHz |
| Slew Rate | 0.8 V/µs - enables accurate reproduction of signals ≤100 kHz with <1% distortion |
| Input Offset Voltage | ±1.5 mV max - ensures ≤15 mV error in 10× gain stage with no trimming |
| Supply Voltage Range | ±1.5 V to ±16 V (or 3 V to 32 V single-supply) - compatible with battery-powered and industrial rails |
| Input Bias Current | 50 pA max - minimizes voltage drop across high-impedance sensor sources |
| CMRR | 80 dB min - rejects common-mode noise in differential sensing configurations |
Pinout & Package
TCM2913J is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package with standard JEDEC MS-012AC footprint, 1.27 mm pitch, and 4.9 mm × 3.9 mm body size.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (A) | Accepts negative feedback or signal inversion path for Channel A |
| 2 | Non-Inverting Input (A) | Reference input for Channel A; high-impedance node for sensor or reference connection |
| 3 | Output (A) | Amplified output of Channel A; drives loads up to 10 kΩ |
| 4 | V– | Negative supply rail connection; must be decoupled near pin |
| 5 | Non-Inverting Input (B) | Reference input for Channel B; electrically isolated from Channel A inputs |
| 6 | Inverting Input (B) | Feedback or signal inversion path for Channel B |
| 7 | Output (B) | Amplified output of Channel B; independent of Channel A output loading |
| 8 | V+ | Positive supply rail connection; shared supply for both channels |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Swings within 20 mV of either rail under 10 kΩ load - preserves dynamic range in low-voltage systems |
| Unity-gain stable | No external compensation required - simplifies layout and reduces BOM count |
| Industrial temperature range | –40°C to +85°C operation - qualified for uncontrolled ambient environments |
| ESD protection | ±2 kV HBM - withstands handling and board assembly without additional protection circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower supply current (600 µA/ch vs. 1.1 mA/ch), but lower GBW (6.4 MHz) and higher input offset (±2 mV) | Better for ultra-low-power battery devices; less suitable for high-precision DC gain stages | Select TLV2462IDR only when supply current is primary constraint and offset tolerance >2 mV is acceptable |
| OPA2340UA | Higher slew rate (20 V/µs), rail-to-rail I/O, but narrower supply range (2.7–5.5 V) and no extended temperature rating | Optimized for 3.3 V embedded systems; not rated for industrial temperature or wide-supply operation | Choose OPA2340UA only for 3.3 V designs requiring fast settling; avoid for ±15 V or –40°C environments |
Compared with TLV2462IDR and OPA2340UA, the TCM2913J uniquely balances wide supply range, industrial temperature qualification, and sub-2 mV offset-making it suitable for mixed-rail, uncontrolled-environment applications where long-term DC stability is critical.

FAQ
What is the maximum supply voltage rating for the TCM2913J?
The TCM2913J supports a maximum supply voltage of ±16 V (or 32 V total across V+ and V–). This allows operation in industrial ±15 V systems and high-headroom single-supply configurations. Exceeding this rating risks permanent damage. The TCM2913J datasheet specifies absolute maximum ratings under "Electrical Characteristics" and must be observed in all PCB layouts and power sequencing plans.
Does the TCM2913J support rail-to-rail input operation?
No, the TCM2913J features rail-to-rail output swing but not rail-to-rail input. Its input common-mode voltage range extends to within 1.5 V of the negative rail and within 2 V of the positive rail. This limitation must be considered when interfacing with low-voltage sensors or reference sources. The TCM2913J maintains specified offset and CMRR only within this validated input range.
Is the TCM2913J qualified for automotive applications?
The TCM2913J is not AEC-Q200 qualified. It is rated for the industrial temperature range (–40°C to +85°C) and meets MIL-PRF-35835 Class Q and Space Level V standards via Rochester's manufacturing process, but lacks automotive-specific stress testing and qualification documentation. For automotive cabin climate control use, system-level validation is required. The TCM2913J remains appropriate for non-safety-critical, temperature-stable subsystems.
Can the TCM2913J drive capacitive loads directly?
The TCM2913J is not optimized for direct capacitive load driving above 100 pF. Stability may degrade with larger loads due to phase margin reduction. For loads >100 pF, a series resistor (≥100 Ω) between output and capacitance is recommended. This isolation technique preserves step response fidelity and prevents oscillation. Refer to the TCM2913J application notes on capacitive load compensation for layout guidance.
What packaging options are available for the TCM2913J?
The TCM2913J is supplied exclusively in an 8-pin SOIC package (JEDEC MS-012AC, 1.27 mm pitch). No alternate packages-including TSSOP, PDIP, or VSSOP-are offered or qualified for this part number. The SOIC-8 footprint is compatible with standard reflow profiles and automated assembly equipment. The TCM2913J's thermal resistance (θJA = 150°C/W) assumes JEDEC-standard PCB copper area.
