STMicroelectronics TS464CN

Overview

TS464CN from STMicroelectronics is a quad rail-to-rail output operational amplifier optimized for low-voltage audio signal conditioning in portable equipment. It operates from 2.7 V to 10 V, delivers ±2.4 V output swing at ±2.5 V supply, exhibits 4 nV/√Hz input noise and 0.003 % THD, and is specified for -20 °C to +70 °C operation - used in microphone pre-amplifiers and multimedia sound cards.

For engineers reviewing the TS464CN datasheet, TS464CN pinout, TS464CN application, or TS464CN equivalent, key selection criteria include rail-to-rail output swing under low supply voltage, input noise floor below 5 nV/√Hz, THD < 0.005 % at 1 kHz, guaranteed operation down to 2.7 V, and TSSOP-14 package compatibility with high-density PCB layouts.

Technical Context

The TS464CN integrates four independent op-amps in a single monolithic silicon die, each featuring complementary input stages enabling rail-to-rail output swing while maintaining stable phase margin into 2 kΩ loads. Its architecture supports unity-gain stability without external compensation.

It uses bipolar input transistors for low voltage noise (4 nV/√Hz) and achieves 8.5–12 MHz gain-bandwidth product with 2.8–4 V/µs slew rate, enabling faithful amplification of audio-band signals up to 20 kHz with minimal distortion.

Key Specifications

Pinout & Package

The TS464CN is housed in a 14-lead TSSOP package (3.6 mm × 6.4 mm, 0.65 mm pitch), RoHS-compliant and ECOPACK® certified, suitable for automated SMT assembly and space-constrained audio modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.

Compared with TLV2464IDR and LMV324IPWR, the TS464CN uniquely combines 4 nV/√Hz noise, 0.003 % THD, and ±2.4 V swing at ±2.5 V - making it the only option among the three qualified for high-fidelity portable audio front-ends requiring simultaneous low noise, low distortion, and wide output swing.

FAQ

Is the TS464CN specified for single-supply operation?

Yes. The TS464CN operates from 2.7 V to 10 V single supply or ±1.35 V to ±5 V dual supply. Its input common-mode range extends from VDD +1.15 V to VCC −1.15 V, and its rail-to-rail output delivers ±2.4 V swing at ±2.5 V, confirming robust single- and split-supply functionality per DS1416 Rev 4 Section 2.

What is the thermal resistance (R_thJA) for the TSSOP-14 package?

The TS464CN in TSSOP-14 has a junction-to-ambient thermal resistance of 100 °C/W, as specified in Table 1 of DS1416 Rev 4. This value assumes standard JEDEC 2-layer board conditions and enables continuous operation at up to 2.8 mA per amplifier (11.2 mA total) without exceeding 150 °C junction temperature at 70 °C ambient.

Does the TS464CN support unity-gain stable operation?

Yes. The TS464CN is internally compensated for unity-gain stability, as confirmed by its 8.5–12 MHz gain-bandwidth product and 2.8–4 V/µs slew rate in Table 3 of DS1416 Rev 4. No external compensation is required when configured as a unity-gain buffer or inverting amplifier with gain ≥ 1.

Are ESD protection ratings provided for the TS464CN?

Yes. Per Table 1 of DS1416 Rev 4, the TS464CN features 2 kV HBM, 200 V MM, and 1.5 kV CDM ESD protection. These ratings apply to all pins and are validated per JESD22-A114, JESD22-A115, and JESD22-C101 standards, supporting safe handling in standard manufacturing environments.
