Product details
Overview
TLV9102IPWR from Texas Instruments is a dual-channel, rail-to-rail input/output, low-power operational amplifier optimized for precision signal conditioning in space- and power-constrained industrial systems. It delivers 1.1-MHz gain-bandwidth, ±300 µV max offset voltage, 120 µA per amplifier quiescent current, and operates from 2.7 V to 16 V supply. It is used in baseband unit (BBU) analog front-ends for sensor signal amplification and filtering.
For engineers reviewing the TLV9102IPWR datasheet, TLV9102IPWR pinout, TLV9102IPWR application, or TLV9102IPWR equivalent, this page provides verified electrical specifications, SOIC-8 package mapping, dual-channel functional context, shutdown timing (11 µs enable / 2.5 µs disable), and real-world application constraints for optical modules and portable test equipment.
Technical Context
The TLV9102IPWR implements a dual-channel CMOS op-amp architecture with independent input stages supporting rail-to-rail common-mode range from (V–) – 0.2 V to (V+) + 0.2 V and output swing within 3 mV of rails under no-load conditions. Its 4.5 V/µs slew rate and 60° phase margin ensure stable unity-gain operation with 20-pF capacitive loads.
Each channel features dedicated noninverting and inverting inputs, shared V+ and V– supplies, and no integrated shutdown-distinguishing it from TLV9102S variants. It lacks channel-specific SHDN pins and relies on external supply control or system-level power sequencing for power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 1.1 MHz - supports stable closed-loop gain up to ~10 at 100 kHz with adequate phase margin |
| Input offset voltage | ±0.3 mV (max) - enables DC-coupled sensor interfaces without trimming in 12-bit systems |
| Quiescent current per channel | 115 µA (typ) - allows dual-channel operation below 250 µA total, suitable for battery-powered instruments |
| Slew rate | 4.5 V/µs - supports 10-V step response settling to 0.1% in 4 µs, usable in pulse-amplifier stages |
| Common-mode rejection | 110 dB (typ) - rejects >99.999% of 60-Hz interference in single-supply transducer interfaces |
| Supply voltage range | 2.7 V to 16 V - interoperable with 3.3-V microcontrollers and 12-V industrial rails without level-shifting |
| Output drive capability | ±80 mA (typ) - directly drives 100-Ω loads or multiple 10-kΩ inputs without buffer stages |
| EMIRR performance | 77 dB at 1.8 GHz - maintains signal integrity in RF-dense macro RRU environments |
Pinout & Package
TLV9102IPWR is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.90 mm, rated for operation from –40°C to +125°C. The exposed pad variant is not used in this part number; thermal path relies on PCB copper pour under leads.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Channel 1 output - rail-to-rail capable, 3-mV headroom at no load, ±80-mA short-circuit tolerant |
| 2 | IN1– | Inverting input, channel 1 - high-impedance (6 TΩ || 1 pF), ±10 pA bias current |
| 3 | IN1+ | Noninverting input, channel 1 - supports common-mode down to (V–) – 0.2 V |
| 4 | V– | Negative supply - reference for both channels; must be connected before applying input signals |
| 5 | IN2+ | Noninverting input, channel 2 - electrically isolated from channel 1 except via shared V– and V+ |
| 6 | IN2– | Inverting input, channel 2 - matched AC/DC performance to IN1– per datasheet characterization |
| 7 | OUT2 | Channel 2 output - identical specs to OUT1; no crosstalk specification given, but tested per channel |
| 8 | V+ | Positive supply - accepts 2.7–16 V; internal ESD protection clamps to rails at ±0.5 V beyond supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2313IDR | Lower GBW (1 MHz vs 1.1 MHz), higher IQ (25 µA/channel vs 115 µA), no EMIRR spec | Better suited for ultra-low-power (<100 µA total) sensor nodes; less robust in RF-noisy RRU environments | Select when supply current is primary constraint and RF immunity is not required |
| LMV358IDR | Higher offset (±3 mV vs ±0.3 mV), lower CMRR (70 dB vs 110 dB), no rail-to-rail input | Acceptable for cost-sensitive AC-coupled audio or general-purpose buffering where DC precision is secondary | Select only for non-precision, low-cost consumer appliance functions-not for BBU or optical modules |
Compared with OPA2313IDR and LMV358IDR, TLV9102IPWR uniquely balances sub-millivolt DC precision, 1.1-MHz bandwidth, and proven 1.8-GHz RF immunity-making it the only option qualified for baseband unit analog signal chains where both accuracy and EMI resilience are mandatory.

FAQ
What is the maximum supply voltage rating for TLV9102IPWR?
The absolute maximum supply voltage for TLV9102IPWR is 20 V (V+ to V–), but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks exceeding safe junction temperature and invalidates parametric guarantees per the datasheet's Recommended Operating Conditions table.
Does TLV9102IPWR include a shutdown function?
No, TLV9102IPWR does not have a shutdown pin. Shutdown functionality is present only in the TLV9102S variants (e.g., TLV9102SIRUGR). TLV9102IPWR requires external supply control or system-level power gating to achieve low-quiescent states.
What is the typical input bias current of TLV9102IPWR?
The typical input bias current of TLV9102IPWR is ±10 pA, measured at 25°C with VCM = V–. This ultra-low value minimizes voltage errors in high-impedance sensor interfaces such as photodiode transimpedance amplifiers or pH electrode buffers.
Can TLV9102IPWR drive capacitive loads without oscillation?
Yes, TLV9102IPWR is specified to drive up to 20 pF capacitive loads stably in unity-gain configuration, with 60° phase margin. For loads >20 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended per Figure 8-3 in the datasheet.
Is TLV9102IPWR qualified for automotive applications?
TLV9102IPWR is not AEC-Q200 qualified. It is specified for industrial operation (–40°C to +125°C), but lacks automotive stress testing, failure-in-time (FIT) reporting, and PPAP documentation. For automotive use, TI recommends the TLV9152-Q1 variant instead.
