Texas Instruments TLV9104IDR

Overview

TLV9104IDR from Texas Instruments is a quad-channel, rail-to-rail input/output operational amplifier optimized for low-power, precision signal conditioning in industrial and communications systems. It delivers 1.1-MHz gain-bandwidth, ±300 µV max input offset voltage, 120 µA per amplifier quiescent current, and operates from 2.7 V to 16 V single supply (±1.35 V to ±8 V dual). It is used in baseband unit (BBU) analog front-ends for sensor signal amplification and filtering.

For engineers reviewing the TLV9104IDR datasheet, TLV9104IDR pinout, TLV9104IDR application, or TLV9104IDR equivalent, this page provides verified electrical specifications, SOIC-14 package details, shutdown timing (t_ON = 11 µs, t_OFF = 2.5 µs), rail-to-rail output swing (≤60 mV from rail at 16 V/10 kΩ), and real-world application context for optical modules and portable test equipment.

Technical Context

The TLV9104IDR integrates four independent high-precision op-amps sharing common supply rails and thermal substrate in a single SOIC-14 package. Its input stage supports rail-to-rail common-mode range (V_– – 0.2 V to V₊ + 0.2 V), enabling direct interfacing with ADCs and DACs operating near supply rails. The architecture includes internal EMI hardening (77 dB EMIRR at 1.8 GHz) and robust output drive (±80 mA short-circuit current).

Each channel features dedicated shutdown control via SHDN12 and SHDN34 pins, allowing grouped enable/disable of channels 1&2 or 3&4 with logic-level compatible thresholds (V_IL ≤ V_– + 0.2 V, V_IH ≥ V_– + 1.1 V). The device maintains 110 dB CMRR over –40°C to 125°C and exhibits low 0.6 µV/°C offset drift for stable DC performance in temperature-varying environments.

Key Specifications

Pinout & Package

TLV9104IDR is housed in a 14-pin SOIC package (body size 8.65 mm × 3.90 mm), RoHS-compliant, with exposed pad option not present in this variant. Pin 11 is V_–, pin 4 is V₊, and pins 6/7 are NC (no connect) - must remain unconnected per datasheet.

FAQ

What is the maximum operating temperature for TLV9104IDR?

The TLV9104IDR is specified for continuous operation from –40°C to +125°C ambient temperature, validated per JEDEC JESD22-A108. This makes it suitable for deployment in macro RRU enclosures and industrial control cabinets where internal temperatures exceed 85°C. All key parameters - including offset voltage drift (±0.6 µV/°C) and CMRR (≥90 dB) - are guaranteed across this full range. Thermal resistance (R_θJA = 105.2°C/W) ensures safe junction temperatures under typical SOIC-14 PCB layouts.

Does TLV9104IDR support single-supply operation?

Yes, TLV9104IDR fully supports single-supply operation from 2.7 V to 16 V, with rail-to-rail input and output capability. Its input common-mode range extends from V_– – 0.2 V to V₊ + 0.2 V, and output swings within 60 mV of both rails at 16 V/10 kΩ. This enables direct interfacing with 3.3 V or 5 V microcontrollers and ADCs without level shifters or dual supplies - a key advantage over legacy op-amps like LM324.

How does the shutdown function work on TLV9104IDR?

TLV9104IDR uses two dedicated shutdown pins: SHDN12 (pin 5) controls amplifiers 1 and 2, while SHDN34 (pin 6) controls amplifiers 3 and 4. A logic-low voltage (≤ V_– + 0.2 V) enables the associated pair; a logic-high (≥ V_– + 1.1 V) disables them. Enable time is 11 µs and disable time is 2.5 µs. During shutdown, output impedance rises to 10 GΩ || 12 pF, isolating downstream circuitry - critical for power-gated sensor nodes.

What is the typical input bias current of TLV9104IDR?

The TLV9104IDR has a typical input bias current of ±10 pA, with a maximum of ±20 pA over temperature. This ultra-low value minimizes voltage errors when driving high-impedance sources such as thermistors, piezoelectric sensors, or pH electrodes. For example, with a 1-MΩ source resistance, the resulting offset error remains below 20 µV - well within the ±300 µV input offset spec - ensuring accuracy in precision measurement front-ends.

Can TLV9104IDR drive capacitive loads?

Yes, TLV9104IDR is characterized for stable operation with capacitive loads up to 100 pF, as confirmed in the "Small-Signal Overshoot vs Capacitive Load" plot (Figure 6-28 of SBOS943E). At 20 pF, overshoot is <5%; at 100 pF, it remains <15%. For loads >100 pF, a series resistor (e.g., 10–50 Ω) between amplifier output and capacitance restores stability. This capability supports direct driving of ADC input capacitors and long PCB traces in BBU analog signal paths.
