Product details
Overview
OPA4354AQPWRQ1 from Texas Instruments is a quad-channel, automotive-grade (AEC-Q100 Grade 1), rail-to-rail input/output CMOS operational amplifier optimized for high-speed video, transimpedance, and ADC/DAC interface applications. It delivers 250MHz unity-gain bandwidth, 150V/μs slew rate, 6.5nV/√Hz input voltage noise, ±100mA output drive, and operates from 2.5V to 5.5V supply across –40°C to +125°C.
For engineers reviewing the OPA4354AQPWRQ1 datasheet, OPA4354AQPWRQ1 pinout, OPA4354AQPWRQ1 application, or OPA4354AQPWRQ1 equivalent, key selection considerations include its quad-channel crosstalk performance (–84dB at 5MHz), 0.1dB gain flatness to 40MHz, differential gain/phase error (0.02%/0.09°), thermal shutdown protection, and TSSOP-14 packaging for space-constrained automotive signal chains.
Technical Context
The OPA4354AQPWRQ1 employs a complementary rail-to-rail input stage (N- and P-channel parallel pairs) enabling common-mode operation 100mV beyond both supply rails, and a class-AB rail-to-rail output stage delivering 100mV from rails into high-impedance loads. Its unity-gain stability and 100MHz GBW product support wideband closed-loop configurations without external compensation.
Designed specifically for single-supply (2.5V–5.5V) or split-supply (±1.25V–±2.75V) operation in automotive environments, it integrates thermal shutdown (trip at 160°C, reset at 140°C), low 3pA input bias current, and robust ESD protection (±2000V HBM, ±250V CDM) - all validated over the full –40°C to +125°C ambient temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 250MHz - enables stable amplification of signals up to 250MHz with G = +1, critical for video line drivers and high-speed ADC buffering. |
| Slew Rate | 150V/μs - supports fast transient response for 2V step signals in ≤30ns (0.1% settling), essential for pulse-based radar and barcode scanning. |
| Input Voltage Noise | 6.5nV/√Hz at 1MHz - minimizes signal degradation in low-level photodiode transimpedance and ultrasound front-ends. |
| Output Drive | ±100mA per channel - drives 75Ω back-terminated video cables or laser diodes directly without external buffers. |
| Rail-to-Rail I/O | Input extends (V–) – 0.1V to (V+) + 0.1V; output swings within 100mV of rails - maximizes dynamic range in 3.3V or 5V single-supply systems. |
| Supply Range | 2.5V to 5.5V - compatible with automotive 3.3V and 5V domains, including battery-backed and start-stop tolerant designs. |
| Quiescent Current | 5mA per channel (typ. at 25°C, 5V) - balances high-speed performance with power efficiency in multi-channel sensor signal conditioning. |
Pinout & Package
TSSOP-14 (PW) package: 5.00mm × 4.40mm body, 0.65mm pitch, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A (Pin 3) | Noninverting input, Channel A | High-impedance node accepting analog signals with rail-to-rail common-mode range; paired with –IN A for differential gain control. |
| –IN A (Pin 2) | Inverting input, Channel A | Feedback path entry point; used with external resistors to set closed-loop gain and configure transimpedance or inverting topologies. |
| OUT A (Pin 1) | Output, Channel A | Class-AB buffered output capable of ±100mA drive; requires series resistor (10–20Ω) when driving >100pF capacitive loads in unity gain. |
| +IN B (Pin 5) | Noninverting input, Channel B | Independent input for second channel; no crosstalk coupling to Channel A beyond specified –84dB at 5MHz. |
| –IN B (Pin 6) | Inverting input, Channel B | Isolated feedback node; supports independent gain configuration per channel without interaction. |
| OUT B (Pin 7) | Output, Channel B | Dedicated output with same drive strength and noise performance as OUT A; shares V+ and V– supplies. |
| +IN C (Pin 10) | Noninverting input, Channel C | Third channel input; identical electrical specs and layout isolation as Channels A/B. |
| –IN C (Pin 9) | Inverting input, Channel C | Third channel feedback node; fully independent per datasheet functional description. |
| OUT C (Pin 8) | Output, Channel C | Third output; verified 0.1dB gain flatness to 40MHz ensures fidelity in RGB video or triple-sensor interfaces. |
| +IN D (Pin 12) | Noninverting input, Channel D | Fourth channel input; supports simultaneous processing of four analog signals (e.g., quad ADC inputs or multi-zone radar). |
| –IN D (Pin 13) | Inverting input, Channel D | Fourth channel feedback node; maintains channel independence per OPAx354-Q1 family design. |
| OUT D (Pin 14) | Output, Channel D | Fourth output; thermal shutdown applies globally but does not disable individual channels. |
| V+ (Pin 4) | Positive supply | Highest potential supply rail; must be decoupled with 100nF ceramic capacitor near pin for high-frequency stability. |
| V– (Pin 11) | Negative supply | Lowest potential supply rail; serves as reference for all four amplifiers; connects to ground in single-supply configurations. |

|---|---|---|---|
| OPA4350EA/250 | 75MHz GBW, 22V/μs slew rate, 12nV/√Hz noise, non-automotive grade | Lacks AEC-Q100 qualification and thermal shutdown; unsuitable for under-hood deployment | Select only for cost-sensitive industrial test equipment where automotive reliability is not required. |
| LMH6629MQX/NOPB | 1.5GHz GBW, 1000V/μs slew rate, 1.9nV/√Hz noise, dual-channel, no rail-to-rail output | Higher bandwidth/noise performance but incompatible pinout and supply range (±5V min); no quad option | Use when >500MHz small-signal bandwidth is mandatory and single-supply rail-to-rail output is not needed. |
Compared with OPA4354AQPWRQ1, OPA4350EA/250 offers lower cost but sacrifices automotive qualification and speed; LMH6629MQX/NOPB delivers superior bandwidth and noise but requires redesign for dual-channel operation, higher supply voltage, and non-rail-to-rail output swing.
